Same. I have a tool to help me memorize key passwords that don’t get daily use (i.e. everything that isn’t my master password), like those for my email, Apple account, etc. If everything burns down, I get the corresponding 2FA backup codes from my parents’ and use the memorized passwords to retrieve my vault. The only cost, aside from (very) occasional snail mail to my parents asking them to just put this piece of paper in their safe, is that I have to memorize 6 passwords instead of 1. And my parents’ phone number.
