This sounds like a comment from someone who lives in a city and doesn’t get out. There is an incredible, vast, mind-boggling amount of empty space in the US. I have flown and driven across the country many times. City dwellers are occupying a fraction of 1% of the space available.
The idea that we must live in hyper-dense cities is utter nonsense. If you like that lifestyle, great, but it’s not reasonable to force it on everyone else.
