I don't see any advantage in the proposed system over oauth-based solutions. Currently, you trust one of some set of big companies to verify your identity, but these big companies might misbehave. The web3 solutions mean that you trust that some blockchain-based approach will be programmed correctly and not have bugs that render it useless; requiring N different people to recover an account will impose unacceptable delays in emergencies.

Better to give one or more nonprofits the job, have them manage identities and do nothing else. No energy-sucking blockchain needed.
