I do not propose cryptocurrencies as uniquely capable of solving the problem. I propose them as actually solving the problem today. Similarly, I don't propose that you *couldn't* travel internationally using a personal jetpack or an ornithopter. I just think that a passenger jet is a likely to be better choice for now.

My experience with international wire transfers so far is that KYC/AML performed at the time of the transaction is cursory. They're just slow because I have to wait for business hours at the sending bank, then wait for the bank to call me (if it's my personal bank rather than my business bank which just sends them automatically), then wait for the funds to make their way to the recipient through intermediary banks who will skim off an unknowable-up-front amount of money.
