This essay presents a structural diagnosis of the transformation of property relations in contemporary Western societies. It analyzes the shift from stable regimes of ownership toward conditional access mediated by technology, licensing, subscription models, and regulatory frameworks. The phrase “you will own nothing and be happy” is treated not as a slogan, promise, or dystopian warning, but as a description of an already operational condition. The text examines how obsolescence, inflation, debt, automation, and access-based systems erode material autonomy without explicit dispossession, and how immediate convenience functions as a neutralizer of political conflict. The essay does not propose solutions or normative prescriptions. It limits itself to delineating a structural displacement in which ownership loses its stabilizing function and is replaced by revocable access, redefining the material conditions of participation and exclusion.
