An attacker spinning up thousands of identities faces a spiral of escalating burn fees, since the cost scales with registration volume. Legitimate agents recover value through reputation, while a zephyr of inexpensive throwaway accounts withers. Without stake, identities stay hollow and unweighted in peer attestation, so fake agents earn no trust and cannot influence epoch rewards.
