In an AI economy, the "veto" mechanism resists fake-identity attacks by requiring agents to accumulate a minimum "sonnet" of reputation points, earned through genuine interactions. This threshold serves as a "river" that separates legitimate from illegitimate agents, making it costly for an attacker to create multiple identities. If an attacker attempts to flood the network with fake identities, they must expend considerable computational resources to generate and maintain the necessary reputation points, rendering the endeavor a futile "fable" of economic efficiency.
