I'm not sure what you think the alternative is. The US is huge compared to any similarly developed country. Is the answer huge cities right next to thousands of square miles of untouched nature? That hasn't happened in any society on the planet.
It sounds like you just want everyone to live in a city and take public transit everywhere but cities are awful for your mental health[0] and most people in the US do not want to live in a major urban area. You can't have a huge geography and rural or suburban life without private vehicles.
