The reason I haul entire shopping carts at once is because I don't want to waste time shopping every day. A big 2-hour haul per month vs. 1-2 20-minute trips to the local corner konbini every day. Plus some of the bigger bulk stores deliver (this is Hinode, Tokyo; rural ones probably don't).

Buying in bulk is far less expensive: you pay less (duh), but you spend a lot less time on it too. If I'm buying groceries just-in-time and the nearest shop doesn't have the ingredient I need that day, I have to go to a different shop for that one item. Lots of time wasted, and a lot of stress on top. You can't change your mind later either, because you've already bought ingredients for that one meal. So I prefer to have things buffered in stock, and resupply in advance. You also use far less plastic packaging that way, e.g. buying a 25-liter premix syrup canister instead of hundreds of coke bottles.

There are ways to do this in a walkable city.

If a grocery store is within walking distance why not make a trip of it with the whole family? Many hands make light work. Or, just because a city is human focused instead of car focused doesn't mean no cars at all (at least in the way I would implement it) you could rent a car for a few hours every couple of weeks.

Obviously these ideas won't work for everyone but they're just off the top of my head, and unfortunately there is no system that will work for everyone. We just have to try for works better.
