No need to be glib. The kinds of situations that are being discussed as the best for blockchain are literally the most intractable - hence why I said it was not a technology solution.
If you're in a situation where cryptocurrency is the best solution for currency, then you're probably in a lawless wasteland with abjectly destructive governance systems.
Seems like in that circumstance moving is the right answer.
I'm not being glib, I'm observing that the global system of passports and visa controls makes "moving" nearly impossible. I nearly pulled it off just over twenty years ago, but I failed, and now I'm permanently stuck back "home". Cryptocurrencies won't help, they're just another way to do capitalism.
