To be clear, I would like to see more mixed use, walkable neighborhoods in the US. I have lived without a car for more than a decade in the US. I've been extremely poor and living in small spaces and spent some years homeless.
You're theorizing. I'm speaking from firsthand experience (plus substantial research).
I'm not theorizing, I'm relaying experience from visiting relatives in San Francisco and NJ, and from staying with friends or for work in DC, Chicago, and Austin at various points. There is of course variety in all those places, but grocery shopping was always a lot less frequent and longer distance that what I was used to (with the exception of a friend who lived alone in DC about 10min walking from a Target).
If you have relatives living in housing in San Francisco etc, those are probably not the kind of housing or demographic or lifestyle I'm trying to talk about here. And if your well heeled relatives can shop infrequently and fill a big fridge and it's an asset to them to have that big fridge, they aren't the demographic I'm talking about.
Please do not tell me what solutions I'm allowed to desire for my country. I don't tell you how you should run things in the Netherlands.
