<p>This paper identifies a structural failure mode underlying modern digital systems: the substitution of temporal order for legitimacy. In many automated infrastructures: financial markets, blockchains, AI agents, and social media platforms; actions execute because time advanced, not because they were explicitly permitted. We argue that this represents a category error: time can order events, but it cannot authorize them.</p> <p>We introduce the concept of temporal control systems, in which execution is triggered solely by temporal progression, and show that such systems are inherently unstable because they lack a mechanism to revoke, pause, or deny action. Drawing on control theory, financial instability, blockchain economics, and AI safety, we demonstrate that this failure mode appears across domains whenever execution is justified by continuity rather than permission.</p> <p>The paper proposes explicit authorization as a missing control primitive and argues that no large-scale automated system can remain stable without it. By reframing recent crises in finance, computation, and attention as failures of temporal authority, the paper provides a unifying structural explanation for instability in digital civilization.</p>
