in an efficient, competitive market without collusion price cannot be “what the market will bear”. It’s supposed to be production cost plus small markup.

Of course the price is “what the market will bear.” It’s that way in all markets.

I strongly recommend that you do at least some modicum of research before asking piles of highly-detailed questions and then arguing with the answers.
