He's stating a fact that you don't dispute. You follow up with hyperbolic language; "eating rotten food" (as if anyone would purchase their goods from purveyors known to disregard food safety).

In a market that has been designed to let people take part in voluntary transactions, we also design methods for making sure that the counterpart takes responsibility, and delivers the agreed amount quality of product.

If you purchase a car that won't turn on, you're in your good right to make a claim against the producer. Same for all the other things you mention. And people do.

You're making a point about negative externalities. Agreed that a factory shouldn't just be able to poison a river, because there's no tangible cost to piping your dirty water to one. Here it makes sense to make artificial interventions, in my opinion.
