Yes, but looking at this only from the perspective of a consumer seems rather limited. One additional consideration, the one we're talking about here, is the importance of being somewhat self-reliant when shit hits the fan.
And even if only consumers matter, what you're saying only hold in theory, given a 'perfect market'. In practice, consumers have imperfect (read: atrociously bad) information, and big corporations hold many unfair advantages.
Unfair advantages, or simply advantages? Companies have a hard enough time surviving in a market where everything is not hitting the fan, their concern about surviving when shit hits the fan is on the fringes of things to worry about.
I absolutely never said consumers are the only thing that matter. I don't know where you read that between my lines. I said that in a market that is propped up by subsidies, the consumer is the one that gets hurt the most.
