Studies show that - particularly in Europe - most people are already walking to these shops everywhere. The 'weekly shop' is not really a thing that inner-city dwellers tend to do that often - they either rely on deliveries (cheap and efficient due to density) or smaller shops throughout the week (which often means less perishables waste.)
Something I wish the holier than though types thought of when they banned plastic bags here. No I can't just keep my reusable bags in the back of my SUV so I have them when I go shopping.
You can have the same lifestyle almost in the states, just live in a downtown area. Watch out for all the cars though, and wading through huge parking lots can still be a problem (I currently live in downtown Bellevue WA, which is only halfway pedestrian friendly, especially compared to Lausanne CH where I lived as a post doc).
That single location remains to this day the only hypermarket in the Netherlands [1].
Lausanne has nice cobble Stone pedestrian only zones, and it is considered more car friendly by European standards (there are lots of car commuters, and lots of people living in suburbs).
Note that there are exceptions where there are stores. However before you point them out, remember that in a generalization there is specifics that are wrong. Even if there are stores, are there enough stores to cover each tiny neighborhood or do a lucky few get stores and the rest have to drive because the stores are not close enough to be useful.
Even red-state St. Louis had a grocery store downtown, though it took a bit to find one near the hotel I was staying at.
I will grant most people I know living in Amsterdam rarely get outdoors into the green, which is why I did own a car when living inside the ring.
