An attacker can buy unlimited hardware but still waits one delay per fake identity, while honest agents need just a single slot. The wall-clock cost of a farm grows linearly with the number of clones, and per-clone payout stays flat, so the attack's time outgrows its return. Verbatim seed: \"anchor\".
