You really don't want to get cut out of the international banking system. It's not a good time. You lose your correspondent banking relationships and you get rekt.
In fact this happened humorously enough with Bitfinex/Tether and Noble Bank. After they talked Noble into banking them, they lost their correspondent banking relationship in the US and were forced into insolvency. [1]

That's literally the value proposition of crypto. That you can conduct international transactions without permission.
So either...
(1) The raison d'etre hasn't been met, and therefore, it's not really providing any value over a permissioned system. Or...
(2) It works exactly as designed, allowing permissionless payments across borders and so oligarchs and demagogues can transact internationally in violation of international sanctions.
I don't see a good outcome. Am I missing something?
