You can't seem to envision anything but a world of cars, mass consumption and long supply chains we currently rely on.

Thinking has to change, lifestyles have to change. People must become more resilient and do business locally. This isn't optional. It's the imminent economic and ecological reality.

Where are you getting your food from? The whole concept of these self-contained cities surrounded by miles and miles of empty land is absurd.

[archetypical]

When you refer to empty land that surrounds cities, are you talking about one of the most underappreciated assets a city could have which is arable land in close proximity to the population?

Arable land may become a valuable economic engine for many cities as peak oil and climate change realities break our current modes of distribution.

Building more roads and tacky exurban houses destroys this valuable land we all may need, and only a few benefit from it (and everyone will pay more in taxes). Think about it.
