If your only idea of "institutional collapse" is "living in a war zone", then I envy you and your sheltered life.

Can you describe a "society collapse" where your cold wallet _can_ get you out of trouble, and why that particular situation isn't subject to "I will shoot your corgi." coercion?

If you're dealing with a peer you can't trust (like the US government) that will ask for your passphrase and then not torture you for it if you refuse, I'd suggest you're not really in a situation where society has broken down.

You've created a strawman. In no point a said "society collapse". I am talking about failing institutions.

You can find on this very same comment section a handful of people who live in places where cryptocurrency enables people to work around failing institutions and/or protect their wealth from systemic corruption.
