To justify Bitcoin specifically you'd need to explain why it in particular should be the one-and-only (or at least, one of a fixed and finite set). A government could do it by fiat, and it wouldn't surprise me to see a government bless some cryptocurrency as its default transaction mechanism. A stablecoin could do it by piggybacking off a government fiat.
It's not impossible that the population as a whole could simply land on Bitcoin, much the way a government exists by the collective consensus of the people living there. But I don't see that as being very likely, since there are too many alternatives. It has the first-mover advantage and might just succeed, but I consider other cryptocurrencies more likely.
This is why Bitcoin, Litecoin, Ether are on top, but other coins will rise as well. This is what we're seeing today - Crypto scaling horizontally to deal with scaling issues and transaction fees.
I don't see any government making a crypto the 'default transaction mechanism' as it would work against the government itself. Being able to control your currency, and print more when need be is what allows a country to manage their long term debt and fund things like large infrastructure projects (or wars etc..)
Crypto is just like gold, just better at storing value than gold in every way - so people are moving over to it. Just as gold doesn't replace cash and credit cards - don't expect crypto to either.
You're right that governments need to be able to deflate their currency, but I don't think that's insurmountable. There are lots of ways to design a manipulateable currency. That would make it less attractive to the people who want a gold standard, but as I said, I'm skeptical about that. While a crypto is like gold, all the cryptos are like the Zimbwean dollars.
Maybe Bitcoin will sweep those away eventually, but for the moment, the imbalance between BTC and the other cryptos makes me wary.
Maybe the system will stabilize on those top 10 coins, and the others will fade out or become irrelevant. But I don't see any particular reason why they would. Most of those 10 ten coins were created in the last three years, and could easily be displaced.
BTC is the granddaddy and could yet be the foundation of a stable basis. But it has enough problems that competitors keep arising, and that makes me skeptical.
You mean Blockstream and Adam Back in particular? Yikes, if that's what you call a good team I'd hate to be on a software project with you. They have severely diviated from the design layed out in the White Paper and Satoshi's intensions of having a cheap, Peer-to-Peer digital currency. The failure to raise the block size alone has been, at best, a massive misstep, at worst, a deliberat sabotage of the Bitcoin project.
Bitcoin is seeing essentially no use as currency (in the sense of medium of exchange, rather than speculative good).
> Unable to be manipulated [...] governments [...] will print trillions on a whim.
Bitcoin do not get printed on a whim, it's true. But this year, Tether volume has increased from $4B to $18B, and the timing of those Tether backed Bitcoin purchases has certainly been awfully convenient for the Bitcoin price.
> I can send thousands of dollars worth of bitcoin
"worth" is doing a lot of work in your sentence. You can convert your dollars into cryptocurrencies quickly. You can transfer the cryptocurrencies at a reasonable speed. But converting the cryptocurrency back into regular money, and the exchange rate at which you will be able to do so, are entirely different questions, and not necessarily ones with favorable answers for the customer.
> Large sums of bitcoin I can securely hold
Unless you have the misfortune to live in an active war zone, I find it hard to think of a LESS safe way to hold large amounts of money than cryptocurrency.
> This entire system is out in the open for inspection.
Yeah, right! The typical crypto company was funded by an Estonian teenager, backed by a consortium of Colombian drug lords, and two years into the operation, it turns out that the only copy of the password to the cold wallet was lost in a botched Visual Basic upgrade, and now the CFO is missing, presumed dead after a luging accident in the Cayman Islands.
Yes tether is useful for moving and storing the dollar equivalent value. The system works for many people and companies everyday. That's why it's growing.
Easy one - A less safe way to hold money in an active war zone is to hold it physically. With crypto you can hold the keys in your head.
Bitcoin system and protocols is open source. No one company controls it. That's not even a debate.
No store of value is safe, do what financial advisors says and diversify evenly across asset classes. It's not about making money, it's about maintaining what you have.
You must be thinking of Bitcoin Cash. Only BCH follows the original design and intention of the Bitcoin White Paper to be Peer-to-Peer digital cash, the BTC chain was co-opted years ago by Blockstream and has been perverted into some wildly expensive settlement layer for their own 2nd layer products.

Why? Because as a currency it's good. There's nothing like it and I challenge you to give me an alternative.
Here's the requirements you need to meet -
* Unable to be manipulated - this rules out most fiat currencies. The recent pandemic shows governments have no self control and will print trillions on a whim.
* Fast to transfer - I can send thousands of dollars worth of bitcoin around the world in under 30 minutes. It takes days for ACH transfers. It takes hours for a wire transfer if you're lucky.
* Cheap to transfer - Compared to wire transfers, transferring bitcoin is cheap.
* I can hold it - I can't store large sums of cash or gold in my pocket (or even my house) safely. Large sums of bitcoin I can securely hold in my phone with my private keys backed up elsewhere.
* Open source - This entire system is out in the open for inspection. No company controls it or can mess with it.
* Battle tested - The fact that people have been trying to break Bitcoin for 10 years now and it still works gives people more confidence to use it as a store of value.
It doesn't matter if it has no value to you. But it has a lot of value to myself and others. If you have an better way let's hear it.
