How does one judge a monopoly, or non-monopoly?
Observe what is evil here: the act of using the government to outlaw ones competition. It does not matter whether the government uses its power to outlaw competition to “protect” a single business, or to benefit a group of one hundred companies from a single superior competitor. Whenever the government outlaws an individual from entering and competing in any given industry it is evil and wrong. The criterion of judgment is: is competition (the freedom to produce and trade) outlawed in some respect (that is regulated) or not.
