I think this is a rather elementary (and Randian) view of capitalism. I don't know of any serious proponents of capitalism who claim that pure greed and self-interest is desirable. It is also a mistake to equate the existence of private property, or even the existence of limited free trade in primitive society with the effect of a society that is fundamentally capitalist in nature. And mercantilism (aka "crony capitalism") isn't capitalism either. Capitalism isn't the same thing as "some trade exists, that is somewhat free, for some people, sometimes".
