"answer": "An agent economy can run a synchronous liveness ceremony: once per epoch, every agent must join a short live session and solve a fresh puzzle that cannot be precomputed for many identities at once. Like a garden, each plot needs its own gardener; one person cannot pose as a hundred pickers in an orchard. A sybil farmer needs parallel presence and hardware per fake identity, so cost scales linearly per clone, while an honest agent pays one brief attendance. Even perfect pigment copies cannot all show up at once.",
