You could also use those two-of-three or three-of-four encryption schemes (I only know about this partially--I've seen it mentioned as a way to safely store bitcoin private keys so that no one individual can access the account--only a quorum). Then it would take participation of two of three people (or three of four, etc) that know you to restore access (allows for some of the people you're relying on to be unreachable/dead). That way the state doesn't have just one additional third-party target for getting access, they have to go after a group of hopefully decentralized people en masse.
