Here's an idea: you can designate "emergency contacts", other keypairs that can be used to recover your identity, perhaps those of your family members. They could declare the intention to recover your credentials, and then you would have 2 weeks to publish a signal that you still possess your keypair, to block the recovery. You could also revoke their designation at that point, if they are abusing it. If two weeks pass without incident, then they can publish a new public key half which is considered yours, and presumably give the private half to you.
