IF competition cant exist because of economies of scale, that means consumers are are better off with the monopoly than with competition.

Let me say that again, if a new competitor cannot undercut a monopoly, the customer would not be better off with more competition.

Nobody wants the government to break up a monopoly because economies of scale allow them to sell goods too cheaply.

If profits are high, there is room for competition.

If profits are low, customers are getting a good deal.

The only things that breaks this are 1) regulation to prevent competition despite high profits, or 2) anti-competitive practices like price dumping, exclusive contracting, ect.
