> The world would probably be a healthier place economically if every town and region could support a strong network of supermarkets, department stores and independent shops.
I don't know what you mean by that. I used to live in a tier 2 European city pre Internet and there were lots of things that were a pain to buy. We'd often have to check multiple stores. Specialty hobbies were served by one or two shops that you had to drive to. I remember having to take the train to a different city to buy a memory card for my computer. There was real consumer cost and societal cost.
The warehouse and online order model is economically a lot more efficient. The real question is what to do with the surplus it generates, make Bezos richer or something else?
