I often get this weird feeling that the world is stretching apart, being pulled in different directions by different forces that both have tremendous value to add. The web is taking over the world of commerce, but I feel like bricks and mortar distributors are required more and more for local business. The web does automatic globalisation, but the one thing it tends to fail at is physical localisation.
If you want to connect with your neighbours, you don't go online, you go to their front door. Local focus is the future of physical presence, while global presence is the focus of the web. If there's more than enough demand locally for your fruits and vegetables, there's no need to sell them online and ship them, besides which they're fresher and more easily available locally.

PS - The same goes for many other local businesses too.
PPS - And limited-interest businesses have to be global to reach enough people.
