Because we all know if a company needs to spend 100mill and a year to bring up a new supply source, their stock price will plummet due to analysts negative ratings.
And I think that's generally true in everything, everywhere. The reason you can walk down the street safely in most places is not because of an implicit agreement of cooperation, but simply because we're all working in our best interest. You don't even consider messing with other people, because you'd just end up in prison for negligible gains. And indeed as soon as that threat and imminence of harsh consequence disappears, it suddenly becomes much less safe to walk down those streets.
BRICS is not united in some ideological conformity, but instead in self interest. They don't want to be dominated by a single hegemon. And I think this form of cooperation based solely on self interest - is far more likely to persist and yield fruitful results. I also expect this is why agreements will, and should, take much longer. Instead of just bum-rushing some virtue filled "Treaty of Whatever" that'll get scrapped by any participating government when it becomes inconvenient, they want to ensure there are implicit self-interest motivated systems driving cooperation through any foreseeable circumstance.
Their primary complaint is that they wish they were hegemons, except to them hegemony means being far more of an asshole to those you dominate than the US's terms. Thus their need to try to force the issue rather than naturally ending up in that position. This is also an issue India and China would conflict on, as being neighbors, they seek to be hegemons over the same region.
They're talking about moving past the USD, but none of them have the trust and general guarantees it has had and none of them are going to risk putting their trade in a currency that would be dependent on the whims of their direct competitors.
I also disagree with your premise that this is comparable to nuclear deterrence. While nukes have been a deterrent to conflict between the US and USSR, Europe and USSR and perhaps also between India and China, they haven't really been a large factor at all in Europe and in Africa.
I think they've been comparatively peaceful not because of nukes, but because European countries were forced to come to terms with the futility of trying to be hegemons over each other over both world wars, with the second one having finally been brutal enough to make them give that up. Now as WW2 fades from living memory, they remain peaceful due to deep integration between cultures that makes it difficult for them to "other" another enough to justify war.
The world order as you know it today is not even remotely "natural." And this is a fundamental component to try to appreciate the geopolitical relations between countries, as well as how other nations are going to perceive the various threats of the world.

In Yemen, the US-led airstrikes have bombed hospitals, markets, etc. as recently as a couple years ago, leading to the largest humanitarian disaster in the world: https://www.washingtonpost.com/investigations/interactive/20...
In multiple countries across Africa, US-trained officers have led numerous coups: https://theintercept.com/2022/03/09/intercepted-podcast-afri...
Yes, it's true that USA seems to have stopped overthrowing governments in South America (if you don't count the coup in Honduras, or our upcoming invasion of Haiti). But countries across south America remember the decades of overthrowing governments and installing our puppets there. And countries across Africa are seeing it today.
Collectively, the "global south" and the "middle east" doesn't have a great view of the USA. So it's not surprising that many of them are joining BRICS as a way to have some allies against US aggression and hegemony, or at least counter its financial dominance with the dollar, world bank and IMF. It's not unlike the governments of countries that experienced USSR's aggression and hegemony seeking to join NATO, in order to have some allies against USSR, and now against Russia. It's not necessary for all their interests to align, in order for some of them to align. "The enemy of their enemy is their friend", is very much in play here.
But you can go further, beyond governments and politicians (as I like to do) and look at polls of regular people around the world. It's not very favorable to USA. Not just "years ago", but let's just look at the last 20 years. The public in our allied countries in Europe named USA as the greatest threat to world peace:

There are plenty of legitimate criticisms of US interventionist foreign policy, but that is largely irrelevant to the global trading system. Money talks, and most of the countries with money (or goods worth trading) are at zero risk of a US invasion.
As for Niger, it's not a member of that bloc nor has it even been invited to join. Regardless of how much uranium they export, they will never have any influence over the international financial and trade settlement system. So, I don't know why you would even bring that up.
BRICS is not about cooperation, but rather about allowing each independent country to fully pursue their own self interest. Right now that's not really possible when relying on economic systems controlled by the US. So we're seeing a gradual shift on the currencies countries hold, US debt holdings, the development of e.g. SWIFT alternatives like SPFS, and so on. The development of a common currency will be the next logical step.
The Chinese re-colonization of Hong Kong (you can go talk to people from Hong Kong and see how they feel about Chinese actions in Hong Kong, if you think I am being hyperbolic) and Xi Xinping's ascension to emperor made it clear that China is an ideological enemy. The Chinese warmongering over Taiwan and the fact that China has become a single point of failure in our supply lines, particularly for PPE has also been quite the wake up call. China's lack of interest in investigating COVID also did not help.
The south china sea and disputed islands with japan are also very much angering countries in Asia who would prefer a "rules based international order" to one where they must pay fealty to China.
We have a colonial history with the phillipines and to some degree they are owed, if not for history, they are owed because of our state departments rhetric about "rules based international orders" instead of "spheres of influence". Taiwan and South Korea are both countries that America could not really do business without. Japan is likely America's closest ally and when no offensive army was made part of their constitution, to some degree that was America making a promise to defend Japan [against China and Russia]. Vietnam is as angry as Philippines over China's south china sea excursions.
The end result is that china is telling us we are an enemy, and our politicians are listening. Xi is beating his chest saying "Asia is our playground, Asia is our sphere of influence" and that is making our allies nervous.
I personally think war is inevitable. The only way war is not inevitable is if china (or ourselves) can be stretched to domestic failure and that can be catalyst for war itself. I think it can be avoided if Xi is ousted by a more liberal leader.
If you think war is inevitable, if your "enemy" is repeatedly saying "we will wage a war of domination against a relatively weak country because we can," what options do you have except to start looking at your supply lines and say "what is our exposure"?
I really can't stress how important China's actions in Hong Kong were. Before China erased rule of law in Hong Kong violating international agreements, there was a lot of suspicion about anti-chinese rhetoric being used to whip up American nationalism, especially regarding Uighers and Organ harvesting. After Hong Kong there is not much doubt any more that China really is evil by western standards and really does want to practice old-world imperialism.

> On 10 June 2022, China's Defence Minister Wei Fenghe warned the United States that "if anyone dares to split Taiwan from China, the Chinese army will definitely not hesitate to start a war no matter the cost."[120] Wei further stated that the PLA "would have no choice but to fight … and crush any attempt of Taiwanese independence, safeguarding national sovereignty and territorial integrity."
Should Russia get its way in Ukraine and China get its way in Taiwan, just because they have bigger armies? Nobody believe russia was going to invade Ukraine until it happened, even after they literally did it in Crimea. Hong Kong was China's Crimea.
I agree, and the other way, in many BRICS and other countries, there is a broad consensus that global economies need to become less dependent on US Dollars.
Both efforts at decentralization and lessening concentration of power are probably going to lead to new good results, as hegemons are forced to compete rather than enjoy a near-monopoly worldwide.
