In my opinion this statement is false when it comes to regulations that limit the ability of monopolies to form.
Monopolies have been a well-proven failure point of capitalism, in that monopolies have the ability to also stifle competition in itself. A large point of net neutrality, as I understand it, is to hinder monopolistic-style traffic shaping that might potentially stifle upstarts.
Already the situation with high speed Internet is pretty bad in this nation -- with few choices in many locations (sometimes only one!), America has one of the highest cost high speed Internet networks among developed nations; high speed Internet providers often are ranked very poorly when it comes to customer service.
