"there is nothing wrong with rightfully earned monopolies." Market dynamics can create an anti-competitive, bad-for-the-economy monopoly without gov't help. Your assertion assumes that there exists no economic barrier so large that it is irrational for a potential competitor to try to overcome it. In fact, there are easy counter-examples: imagine a town's public water source dries up and the only well is owned by a purely rational/greedy party.
