What kind of vehicle do you think usually pulls up to a loading dock?
Grocery stores inside cities do not have loading docks. Their goods are typically delivered by this type of vehicle to curb-side offloading sites during off-peak hours.

Here’s a grocery store. It’s in downtown Little Rock (pop 204k).
Bet you anything you like all that cardboard got hauled away in an 18 wheeler (or a recycling truck).
To be clear (and reitierate) I’m not talking about heavily urbanized places, I’m talking about moderately urbanized places (which there are a lot more of). Converting a few inner city blocks in super dense cities is entirely meaningless in terms of helping the environment. For a solution/change to be useful, it will need to have wider applicability (to the majority of cities, which have <1m pop).

Such places exist as a direct consequence of car culture. Their existence is not a universal constant; they can and must be turned into heavily urbanized areas.
Their existence is not a universal constant
Their existence is far more constant than heavily urbanized areas.
they can and must be turned into heaviliy urbanized areas
This is highly unrealistic. Most people do not want to be packed in tighter with other people, they want more space not less.
