> Strong competition would mean dozens to hundreds of sustainable entrants.

Absolutely not, there is such a thing as minimum efficient scale. Some markets might only have room for 2 or 3 companies to operate efficiently.

I agree with you, but this idea undermines the justification of the free market.

[ucaetano]

Nope. It doesn't in any way.

A free market is one where prices are set based on supply and demand without restrictions on competition due to monopolistic powers, market reserve regulations, etc.

There are always limits to competition, some due to scale, some due to market size, some due to availability of resources. None of those prevent a market from being free.

Even antitrust regulation doesn't necessarily prevent a market from being free.
