You'd probably want to use diversity for this - do 2of3 multisig with a Coldcard, a Ledger, and a Trezor.

Yes, but the complexity of the setup (which is already way too much for any non-cypherpunk normies) is starting to get kind of ridiculous.

I am still pro crypto and fascinated by the technology but we have to admit the original cypherpunk vision was unfortunately never going to work, we're going to end up with something else
