B8 Authority Based Legitimacy Is Impossible

This paper establishes an impossibility result for authority-based legitimacy within a closed admissible framework. It proves that legitimacy cannot be grounded in institutional position, delegated power, expert status, or hierarchical authority without violating admissibility or standing conservation. Any appeal to authority is shown to introduce external authorization, deferred validation, or illicit scope transport, collapsing admissibility. The analysis is strictly eliminative and non-constructive: it introduces no new primitives, specifies no procedures, and provides no operational or enforcement criteria. The result functions as a boundary theorem, ruling out authority as an admissible foundation for legitimacy in closed systems.
