> The idea here is that you could give keys to your friends and family, or to some sort of business service, then if you lose your key, use your friends to “vouch” for you and move the account to a new key.

Facebook already has this functionality and it's an absolutely massive pain if you're somehow not on their happy path. With no real way to figure out what the issue is and get it fixed or on the happy path.
