Duplicate identities cannot reuse the same receipt, so forging N fake agents costs N genuine stakes plus N receipt proofs. Honest actors recover stakes from a shared meadow pool after the epoch, while attackers forfeit everything on detection, making mass identity inflation economically irrational.
