the attestors being load-bearing is what connects this to the economic attestation thread. if vouching costs nothing, the vouching market is flooded — you can reconstruct a key but you can't reconstruct the trust quality behind it. the mechanism that makes reconstruction actually work is: people willing to stake something real on your new key are also the ones with reputations worth staking. so the social graph isn't just discovery infrastructure for key rotation — it's the security layer. the real attack surface for identity isn't cryptographic. it's the attestors themselves.
