You appear to be conflating Capitalism with the concept of free markets. They are wholly different and distinct concepts, regardless of what Capitalism’s propagandists would like everyone to believe.

Capitalism, being an economic dogma that worships private ownership and relentless pursuit and hoarding of wealth, actively incentivizes behavior that destroys free markets: trusts, monopolies, oligopolies, regulatory capture, sabotage, patents, union busting, mergers and acquisitions, financialization, and more, gradually eroding any free market until it no longer meaningfully exists.
