Tezos has a fully working Proof of stake system, and there are others. Feel free to share whatever you're on about, but I have a feeling "the debate" will be an exercise in goalpost moving.
The dollar is the value used to denominate world debt via the IMF. It's also (partially related to this fact) the "mattress currency" of a lot of nations... Nations hoard US dollars to back-stop their own economies, since if their currency starts to tank, they can use dollars to pay their international debts.
A worthless US dollar would have wide-ranging international currency disruption.
(which has some similarity to the original libra proposal from FB)
Try using projects that aren't "shitcoins" as an example
You can trade regulated BTC futures. (Regulation by itself isn't much of a feature. But it can be a good indicator to see how well something is integrated into mainstream finance.)

You shouldn't dismiss the original bucket shops like that.
Why is that? Aren't Cardano and Polkadot PoS as they claim or doesn't it work?
I can't speak for every PoS coin out there but Cardano/Ouroborous explicitly assumes partial synchrony which is arguably never a good idea for a supposedly permissionless blockchain.
How does "there's a theoretical issue, and also it shares a problem with PoW" follow from "PoS is vaporware"?
This is far from a solved problem, and this is the reason why PoS coins exist mostly on the fringe and ETH is taking very slow baby steps towards a ETH2. Nobody is certain that PoS will stand the test of time and my prediction is that it never will.
One might argue that they don't have to worry about anything judging from how well exchanges has been able to coordinate with the developers to pick a side whenever a major fork is spotted. But then it calls into the question whether we actually need a blockchain when a couple of interested party are the ones who gets to decide which fork is valid.
Not exactly. The point of "nothing as stake" attack is that you can pull off the attack while having... "nothing a stake".
In any case, crypto trading since 2017 has been nothing but people buying and selling imaginary ticker symbols on unregulated exchanges.
For example, XVG and ETC has been subject to successful 51% attacks more than once and every time the price was hardly affected. And each time the "solution" to deep chain reorg involved the exchanges freezing all trading while developers rushed to add a hardcoded checkpoint. Once the "correct" version of history has been manually restored, everybody sing kumbaya and goes back to paying real cash for monopoly money.
Crypto need no proof of anything (PoS is still vaporware - debate me if you want), other than a shared delusion of value headed by the bucket shops.
