Using legal structures are efficient just like we don't build our own hardware wallets and computer OS.

The beauty with Bitcoin is that it is so easy to self-custody that a company/individual/entity in a country where they distrust the regime could make that decision for themselves.

Or in the USA, if no one likes the results of the election, the ETFs could be sold as self-custody could be bought. And that can happen overnight or in anticipation of any event.

It's a risk/benefit analysis and it's a different calculation for each entity, jurisdiction, time.
