All of these urbanist types always come to the exact same collectivist conclusions. It treats human culture as a mathematical optimization problem, which it isn't. Everything would just be so much better if we all lived in 20 story 800sqft apartments and took the bus everywhere.
I don't want to live like that. I want a car, maybe two for my family so that we can go where we want when we want. I want a home large enough to entertain friends, host holidays, and house my children. I want a yard with grass, and I want to spend my saturday mornings mowing it. And I think that's exactly what most other Americans want.
There has to be a solution that doesn't involve the loss of individual autonomy, privacy, and freedom that we value in the US. I will not eat the bugs. I will not get into the pod.
