No human economy can be other than a political economy.
Human political economy follows the laws of dismoral post hoc rationalizing memes that justify hierarchy and acquisition, not the laws of nature. It is an epiphenomenon of the real, thermodynamic economy, which follows the laws of physics and natural selection. The real economy is constrained by the limits of a finite planet. Our current global political economy believes there are no constraints; it does not believe in limits.
