All those things are awesome (if you're into that sort of thing, many people aren't) but they don't really rely on the car. Many of the low density detached home suburbs that people drive to these days were once upon a time street car suburbs.

But answering the question, "what's not to like?" The main thing is the fact that none of this scales. All the good benefits you're describing rely on the fact that other people aren't doing them. Other people need to live in "cages" so that you can have all this extra space.

Similarly an enjoyable experience in a car free of traffic relies on other people not driving. If all the people that are using transit were driving a single car, the traffic congestion would spike and you'd be in misery.

None of it scales due to the unchangable dynamics of physical geometry.
