I heard about Argentinian ban of selling bitcoin before, but am surprised it is kind of retroactive in that users cannot withdraw already bought btc. Needless to say, such retroactivity is only possible with those beloved custodians.

Perhaps Liquid could help about this particular risk (restrictions imposed by government). And it has proof of reserves built-in. Still custodial, but needs majority of the federation members to be coerced, so various governments would need to cooperate. Should protect against local crisis, wouldn't be so sure about a global crisis.
