Doesn't this kind of argument prove too much?
Consider an alternate reality without food standards and regulations. Things like the melamine incident are commonplace and people regularly suffer due to contaminated food. Someone argues "perhaps the corporations should stop poisoning our food". Then someone else responds "Stop demonizing the executives, their objective is to make a profit, which they get from the consumers. The consumers are the ones buying the contaminated food, the executives aren't. If people don't want to get sick, they should exercise more diligence."
It's easy to offload coordination problems on the people who make imperfect decisions as a consequence, but saying "just don't have coordination problems, then" is rarely useful if one wants to mitigate those problems.
