About levelling the playing field, the problem is regulation in general. Monopolies are only bad if they are supported by violence=governments (for example you could consider Google a monopoly but it's a market based one). You don't need a lot of competition, just remove all regulatory barriers to entry/exit (note: barriers to exit are also important).
