It's not much different than the problem of micronations[1]. Exciting as they are for D&Ders of a sort, they aren't real nations for the simple reason that they lack a defining feature of a nation (among others): that everyone else think they're a nation.
Cryptocurrency is perhaps not as extreme; a reasonably large number of people appear to be persuaded that units of cryptocurrency are a real asset, and some begrudging convertibility into other kinds of assets (a defining feature of a currency) does exist. Still, it suffers from a similar problem, in kind if not in degree.
This is the difficult part for me with Cryptocurrency. Sure, the idea is cool, but I can't really use crypto with any of the services I use except for maybe my VPS provider or other technical services (which requires me to provide an email address anyway). I'd love to hear about mainstream services allowing financial transactions through cryptocurrency. Pornhub is the only mainstream/non-tech service I can think of.
The only practical use for me with cryptocurrency would be to convert it back into USD eventually.
I suspect those may have been edge cases though.
Let's not assume that it's going to be the end-all and be-all, because it's not. It's a medium of exchange between members of a community (BTC, ETH, Doge, or whatever).
The common misconception that "oh crypto is such a scam" type of group is that they assume this is designed to replace something else. It's not a replacement of any kind, it's a tool for a medium of exchange between communities.
Permissionless means that there is no central entity needed to observe or even approve my actions with my assets.
What existing solutions?
I strongly disagree, self-soverignty is a personal decision. It doesn't matter in what country you live.
