Sure, hyper-dense cities are not ideal, but neither are spread-out asphalt wastelands where cars are the only means of getting around. This is terrible for anyone who can’t drive (children, people with impaired vision, people who can’t afford cars). I have also lived in Houston (without a car) and I found getting around absolutely miserable. Even when I had friends pick me up with their cars, the distances were huge and a lot of the time, this would be because of parking lots creating gigantic empty space everywhere. (At least, this was my impression.)
