> Capitalism is built around competition and anti-monopoly, philosophically

No, it's built around centralization and rent-extracting monopoly power moving from the feudal aristocracy to the mercantile (now “capitalist") class, motivationally and historically. The risible competitive and anti-monopoly argument that bears no resemblance to the facts (anti-monopoly controls were one of the major elements of reactions against capitalism once it had reached it's maturity) was a later post-hoc rationalization.
