Earlier quoted context omitted.
People are in denial about aging out of city living.
Why would you age out of having amenities closer to you? If anything, as you get older things should be even closer.
Also, the amenities available in a city are quite limited as you age out of your 20s. Food and necessities become a much smaller share of what you are purchasing. Eventually you want access to tools and hobby supplies and home goods - stuff that is logistically not hauled into big cities but dropped off in the suburbs.
