Your comment read to me like this “not everyone likes urban environments, people don’t want [insert thing indicative of the suburbs] right on top of them”
Urban places aren’t just more compact versions of the suburbs.
Suburban tends to be not generally walkable because grocery and retail tend to be on the outskirts and not city center. My comment about big box stores was meant to basically convey that they are not walkable or bicycle friendly because folks in suburban environments don’t want those giant stores that near their homes, but they don’t mind and actually prefer them to be 5-10 by car.
Some neighborhood developers drop quasi downtown main streets now with a few restaurants, boutique shops,etc…but these are not designed to sustain the community around it, but more as a neighborhood perk. Generally are nice enough that nearby homes are not devalued by close proximity the way a large retail or grocery store might be.
