So, we define the market as that system containing everything that is (apparently) part of the market. However, the counterargument here would be that things outside of the market system, unlike the pot and flame, do effect what is in the system. That is, the “commons” outside of the market (into which things may be dumped or extracted) apparently play a role. To the extent such commons are artificial in nature (“public” spaces) and thus through state coercion the market’s efforts to allocate and economize those resources via private property are frustrated, we cannot say then that any abuse of such spaces is a market failure. The state itself is setting up the very situation that opens them up to abuse. The state is not part of the market. The market is peaceful voluntary trade where both parties “win”; the state is violent involuntary trade where one side wins and one side loses.
