FIAT is always in trouble, now the only additional problem is inflation, which surprised many with its numbers, and now everything looks much worse than 2-3 years ago. The problem that the OP and many others have is that they think that countries should be even more tolerant towards Bitcoin, especially if they are referring to the EU, which so far has not caused problems for anyone who wanted to use Bitcoin in one way or another.
Bitcoin is only an alternative currency that cannot be a solution to the problem, even if the entire EU declares it legal tender - the problem still remains. The system is rotten, no doubt about it, but to change it, it would have to completely crash and reset. But if it were to happen, many would wish it had never happened considering the consequences it would cause.
...like the US were there are over 46m users and roughly 22% of the adult population own a share of Bitcoin, there can still be a number of digital assets and the Fiat currency but the govt would recognize both of them.
Do you think these data are correct? Who published them - the IRS, the state statistics office or perhaps some CEX? To me, that seems overblown, just like the numbers coming from Nigeria or India. When you add up all those millions around the world, it turns out that 20% or more of the world's population owns Bitcoin or cryptocurrencies, and that brings us to 1.6 billion people, which cannot possibly be correct.
