Pure unregulated market, that doesn't guarantee free market assumptions does that. Capitalism doesn't need it. Without mechanisms that allow for the free entry/exit of competitors, fair and simultaneous access to information, preventing cartels/price fixing, .... a bunch of assumptions for perfect free market to happen, the market will tend towards monopolies due cumulative advantage (in econ. known as Matthew effect), since small advantages compound into dominance.
