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.

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.
