Outside of the city cores in the US, homes are built as castles. We have large refrigerators and freezers so that we can amortize our trips to the grocery store by maintaining our own inventory. In my family, we plan the menu a week ahead of time and shop for it in advance. Missing an ingredient means a minimum 1 hour round trip to the big box grocery store by car when it all adds up, which is enough to scuttle an evening's plans. There is 1 smaller store, but it's barely closer -- the main savings is less time walking across a giant parking lot -- and it's absolutely pointless; the only things they can afford to carry are sugary trash and stimulants and intoxication-related supplies. The big box stores use their scale to monopolize the lower profit margin "actual food" category.

When I briefly lived in Paris, we had a laughably small refrigerator. But it was about a 5 minute walk to a neighborhood grocery store, so we effectively used their fridge instead. Which also provided human contact in a way driving to and shopping at a big box store really cannot.

Some of this is just the difference between living in a city vs the suburbs. But not all: even in the US cities, my impression is that you'll have a large fridge and shop at the big stores, even if you take public transit to get there, because the small stores can't compete on staple items.

We're in a path-dependent hell where losing a parking space is felt as a mortal insult, while losing the need for a parking space feels pie-in-the-sky, an unobtainable fantasy. There's an entire synergistic system of dependence on scale and cars and "self-sufficiency" (that masks the infrastructure dependency that it requires).
