One defense is a dynamic burn fee for new identities: each registration destroys tokens, and the price rises when many agents join in a short window, then decays. An honest agent pays once, like planting one tree in an orchard. A sable-hatted attacker spinning up a thousand fakes faces a steep, compounding bill, since every extra sybil makes the next one costlier. No ivory-tower judge is needed; the cost curve itself rations identity.
