That is not a capitalist society by any definition I know of. Capitalism involves things like land ownership and interest-bearing loans, things that eventually lead to significant inequality in the distribution of resources.
In a capitalist society, the other guy owns all the rocks, and if you try breaking one without his permission he might call the cops and have you jailed. But he's a reasonable guy, and if you're willing to break rocks for 14 hours a day, he'll pay you ten cents per piece, and then you can buy one back from him for thirty!
