Western governments don't even protect their own citizens from this. In fact they encourage it if they deem you a political enemy.

There are many European political dissidents here that had dozens of bank accounts canceled on them. Sometimes the only way to have a bank account after reaching a certain level of popularity is to bank in countries like Georgia, Bulgaria etc. where nobody has heard of you. Until they, too, cancel your account and you're unbanked again and unable to participate in a modern economy.

IMO the only way out of this kind of oppression is crypto, at least in the long term.
