The credit card one is a good one, credit cards are the worst possible approach I can imagine to transact money with. Forex exchange is pretty cheap these days with things like Wise. You can technically charge your debit / credit card just by knowing the number. All the others are political problems and they can't beat a state actor. Eg. You won't stop the government from seizing your assets: they'll put you in jail until you give them up. We should think about a political solution, not a technical one (I'm all for abolishing the government). I'm surprised they didn't crack down on crypto earlier, I suspect they're using it as a sort of inflationary device. Having extra unbacked crypto in the world means you have more money in the world, making the rest of the money a little bit less valuable - but I don't think crypto was considered seriously enough to affect fiat, at the beginning. Now, when you want to push your currency or local assets up you can just ban/harm crypto (which is what Russia proposed with the RUB going down a month ago).
