Downtown and inner core retail/commercial space is far too expensive now for small groceries to flourish the way they once did in the long-ago past. Even the large chains like a 711 or Circle K are few and far between downtown due to the operating costs. Moving large delivery trucks around confined and crowded core streets, avenues, and alleys is a genuine hassle as well, especially for the drivers who have to maneuver something like a 14 or 18 wheeler for a large drop-off at a store. And the culture of driving, that the vast majority of people still engage in, makes it even more certain that most people will take the fastest option of stopping at a large suburban store on the way home from work or on the weekend to get what they need, as opposed to going to the city core to "enjoy the urban ambience".
I know a lot of these ideas have a certain romance to them, at least to the fans of the think-tank groups who dream them up. Realistically though? They're little to no help when it comes to realistic changes. I can see online grocery shopping becoming far more of a real-life option than I can seen new chains or independent stores suddenly appearing in numbers large enough to be considered an increase in competition.
Good points to bring up. A smallish store wouldn't necessarily have the advantage of a loading dock or even a reasonable parking space for a trailer to offload to easily.
I know someone who does deliveries for folks who shop online for groceries. I just can't see myself shopping this way for groceries though. It's easy to pick out things like canned whatever or a box of pasta or cereal but I wouldn't want someone picking out my produce or meat as those are things I need to see for myself.
