This has always been the drama of urbanism. Only a minority is pushing for it, while the rest furiously resist thanks to years of car-centric propaganda (and vested interests).
To me, I think if this generation had to choose between same day delivery and walkable neighborhoods they're going for the former. Maybe that's a false dichotomy
This generation is a lot of people, and who is to say they can't have both? Same day delivery becomes easier in densely populated areas, and densely populated areas tend to be more walkable.
