paris proper is already one of the densest areas in the world (and definitely in europe). when i lived there i wouldn't have noticed any problems with crowded grocery stores or community spaces compared to the comparatively low-density city i currently live in.
there definitely were a lot more people in the streets, other cities feel deserted in comparison.
Delivery also lets you have more smaller stores carrying the 80% you need regularly, and the 20% that is less common can come via delivery in a day or two.
