That's one of the stupidest things I've seen written.
Cities existed long before cars. People didn't have to carry a weeks worth of groceries because the groceries came to them. A daily walk to the town market was enough to satisfy the need for food.
The law of supply and demand was developed on observing prices at these food markets, btw.

Oh, my. Did I upset your Marxist dreamscape of human worker ants crammed into squalid big city hellholes?
