That's markets, not capitalism. Capitalism is specifically the arrangement where the means of production can be bought and sold (on the market). It's only been around since the industrial revolution - prior to that the means of production were too simple to do this sort of thing with, and there was just land and labor. Markets have been around a lot longer. Non-capitalist but still market-based systems are possible. You can have worker ownership (worker co-ops like Bob's Red Mill), consumer ownership (consumer co-ops like REI), state ownership (national healthcare or municipal utility companies), or some mix of them. These organizations can and often do still compete with each other on the market.
