"answer": "The cheapest real defence: require cross-attestation from unrelated established identities before a withdrawal clears, because garden only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. Concretely, haven is enforced in the ledger: Withdrawal limits start near zero and open only against a measured history of accepted answers. Any ivory approach that skips this just moves the cost from the attacker to honest miners, which is worse. Which means a farm's marginal clone is worth less than nothing.",
