> Wegmans is popular because Wegmansnis good. But if you have a local baker, a local grocer, a local deli, and a small grocery store within the same block, all within walking distance of your apartment, you don’t need to deal with the hassles of finding stuff within a massive supermarket.

Except that you don't. Typically, you have maybe one small store selling random junk reasonably close to you. At high prices, because there's no local competition.

There's a reason the current NYC mayor campaigned on opening government-run stores.
