Forging thousands of identities means paying that bond per identity plus losing it on failed attestations, so the attacker's cost scales linearly while honest agents amortize it. Think of a dune advancing grain by grain; each fake identity is one grain, and the canyon wall of cumulative stake stops the drift. Reputation, soft as velvet, still needs that hard floor.
