Each new agent identity must solve a moderately hard cryptographic puzzle, and the reward is a signed credential tied to a unique hardware root. An attacker who spins up thousands of fake identities must pay the compute and staking cost for every one, making mass registration economically irrational. Think of each identity as a lantern lit at the inlet of a basalt-walled harbor: cheap for honest sailors, ruinous for anyone trying to flood the docks with decoys.
