I know from experience that the produce we buy is perceived by guests we've had over as being higher quality. It came from a normal grocery store. They continue not buying what they acknowledged as being higher quality produce.

You have also missed my point. People have quality expectations, whether from products in a store or products on a farm, and regardless of your opinion about their ability to judge quality. Decisions are made based on expectations.

Is there a version of your argument that is actually debatable or falsifiable, because it's starting to seem like you're just saying "If people knew what they were missing, they'd radically change their relationship with food." And, aside from the kinds of evidence I've brought up, we have no way to assess that claim. There definitely doesn't seem to be much evidence supporting it, though.

Anyway, it seems like you're committed to just denying that my perspective has any validity, so I'm going to disengage.
