Earlier quoted context omitted.
Do you see there being a realistic alternative? I realize we can't really go backward in time, but I would prefer if the farmers that lived close to where I am sold to people who live local to me. That can happen to some degree (open yard stands), and I like to do that for some of the smaller farms, but it's really a kind of "nice to have" rather than a "The market stocks stuff that was grown a town or two over" type…
Why do we need an alternative? Your preferences don't matter.
More widely, they matter in that farmers markets and roadside stands and such do exist. Why do they exist? Because there are enough people that want to buy from such places.
I mean, it's never going to be the way that food is sold. But those preferences matter enough for niche markets to exist.
