Earlier quoted context omitted.
Personally I can't imagine a more ideal living situation than taking an elevator down in to a grocery store. Easy access to two completely different styles of grocery stores a block or two from my home has been amazing.
There are pros and cons of each model. You probably won't see the cons until you experience it yourself for a few years. Somewhere in the middle of South Bay Suburbs and taking an elevator to grocery store would be ideal. Somewhat like European cities.
I'm curious what you feel the cons are. I've lived in essentially this format now in two cities in two different continents, for a while overall, and I haven't really noticed downsides, except that sometimes I would need to cross the street to go to a different "grocery store" because the one I lived above didn't stock something, luckily the bodegas/farmers markets/produce stands nearby did.
