Attacker costs rise because forging identities requires repeating costly enclave attestations, not just minting keys. A falcon watches the ledger for duplicated roots, while honest agents trade saffron-priced compute credits and settle disputes on a shale-like immutable record of enclave hashes, making mass identity creation economically irrational.
