Ugh, ok, almost every assumption you made was not correct.

Vanguard and fidelity will absolutely comply with any banking freeze, and if they didnt, theyd be sanctioned into the dirt. Thats what makes US sanctions so effective, is 97% of world financial transactions route through our servers. That gets shut off.

If you have faith in the FDIC then youre protected for $250k in government insurance, but inflation eats that quick.

In a scenario where things are so bad that the US has halted all financial electronic transactions than your electronic dollars don’t mean anything no matter where you are, amd your paper dollars mean almost nothing either.

Flyings fine as long as I have variable velocity.
