#BIP39 with a good passphrase is 2-of-2 multisig that is totally unencumbered from the need to backup metadata.
Discussion
True. Multisig seems to solve a couple perhaps important problems for me:
1) someone finding one of my seeds (accidentally or intentionally)
2) vendor risk for a hardware wallet - both in the seed generation process and the signing process
3) Someone trying a $5 wrench is tough since I would need to travel to multiple locations to move anything
I still am not sure if the trade off is truly worth it. I like the idea of just being able to roll anytime with 12 words and a pass phrase as opposed to all the crap I’d need to move with my multisig
