Capitalism and free markets are separate things within the economic “sphere” of society. Capitalism is an economic doctrine that focuses on directing production through private capital; free markets (in theory) ensure “equal access” to markets for products (as compared to monopoly or (economic, not necessarily drug) cartel markets which restrict access).

Over in the “public sphere”, governments decide whether to jump in bed with private capital (often resulting in monopolies or cartels in economic marketplacs), or to make & enforce regulations that protect the (so-called) free market.

Or to make and enforce regulations that protect consumers – i.e. human f-ing beings – and enrich local economies without protectionism and “zero sum games”, but I guess we shouldn’t get too carried away here ;)
