People who like dense living spaces should visit some of the dense high rise areas in Manila. Enjoy the gridlock and queueing ten minutes for the elevator to your floor.
So, be honest and just compare suburban sprawl against, well, normal development where people can build town houses, duplexes, small apartment buildings, and of course small stores and restaurants. THAT is the density that the majority of people are talking about. Not high rises in ultra dense urban cores. I think more Americans than you think would like to be walking distance from a decent grocery store, bar, and breakfast place. I enjoy it!
