Aesthetic Value as Economic Substance
Postrel's thesis that look and feel are not decoration applied to economic goods but constitutive of value itself—when removed, the product is not simplified but transformed into something lesser.

Removing aesthetic quality does not return a product to its functional essence—it produces a different product whose diminished aesthetic character makes it economically and experientially inferior. Postrel demonstrated this through market behavior: consumers pay substantial, consistent premiums for beauty; companies investing in design outperform competitors; brand loyalty is fundamentally aesthetic loyalty. The iPhone's success despite functional parity with competitors, Starbucks's premium for experiential environment, Dyson's sustained pricing power—all empirical confirmations. The AI revolution completed the proof: when functional execution becomes universally accessible, aesthetic quality remains as the sole sustainable differentiator. Markets have spoken with clarity: the substance is the style.
