You can believe that all you want, but this is an even nutter dream than achieving effective gun control in the US (one of my nutty dreams). Why in the world would the government ever give up control of the “money supply”? That’s not going to happen.
Governments have shown in the past they will indeed never give up their money printer. That’s a key reason crypto was created. You seem to think governments are willingly allowing crypto to exist and have the ability to shut it down. Centralised e-cash has been tried (and quickly squashed). P2P crypto is immutable and exists to preserve the freedom of users.
They have the ability to shut it down for all practical purposes by simply banning its use for transaction by legitimate companies in their country.
Oh, they’re absolutely not going to give it up. That’s for sure. But as a citizen, you can just stop using it as much as you can in your day-to-day life. You can’t avoid using it entirely in most cases, but you can tone down how much you use it pretty significantly. And that they cannot control.
