But how do you store the password to decrypt the cloud backup?
First in your brain, maybe with anothet highly trusted human, then backed up in a bank vault in a completely different location, like other side of country, in the rare chance you die/lose memory

Don't do that, read the answer about keeping a decryption key there
On its own any banker doesn't know what it opens or the location of the encrypted material
