Mafia is what you’re describing, not dictators.

Good luck going door to door getting BTC from people with multi-sig setups in more than one jurisdiction, multiple accounts with different passphrases, when you don’t even know what or if they have any.

And even if that did start to happen, people would move their holdings to complex multi-sig, multi-jurisdiction where it’s untouchable via violence en masse.

And that’s assuming people with resources didn’t organize to defend themselves which they also would.

I’m not against gaming out some worst-case scenarios for which to prepare, but the baseline should be — how am I going to impose my will on the corrupt and unjust state, not how is it going to exploit and dominate me.
