>"Isn't a completely free market likely to collapse onto one or two dominant suppliers who then prevent future competition by restrictive practices?" I have never seen any evidence of this, though I would be interested in reading any material(s) you have supporting this position. The only successful long-term monopolies and oligopolies which keep prices high, or increase them, of which I can find examples are government-supported, either through regulation, subsidy, or protectionism. Some companies manage to keep their position at the top of a market without government support, by constantly lowering their prices, or improving their product offerings (i.e. Amazon AWS, and Google search), but I would hesitate to call these monopolies, because a new entrant could disrupt them at any time, and these companies do not appear to be 'exploiting' a guaranteed market.
