While I love the V for Vendetta reference here, our situation isn't as dire as you seem to make it. The state already lost 5 years ago when 1 Bitcoin was worth more than 1 €/$. That was the time when they should have cracked down on everyone just saying Bitcoin.
But they were arrogant and Pandora's box is open now. The Idea of Cryptocurrency is spreading and no one can stop it anymore. Or how do you want to shut down more than 1000 of them?

Also States now are in a bad position. The have to please the crypto crowd so they don't flee their country. Our main focus now should be to take a good look at cryptoheads who join forces with governments and stay as far as possible away from them.

So don't get me wrong, I love your post. And your friend is right: Taxation is slavery.
