Your line of reasoning is downplaying the fact that we don't exist in a world with perfect markets or rational consumption habits.

There are multiple clear cut examples of producer collusion and oligopoly formation in the past few years - including in the food industries (see eggs and pork in the past 5 years). Food being essential for life means consumers can't interact with the market rationally, just like they can't for insulin, transportation that enables income, and so on.
