It's basically about the infrastructure cost and higher density actually helps a lot to reduce this cost and make the system more sustainable. Yes, theoretically you can have good infra without high density, but it will cost much more. There's a good reason why the most dense cities in the world (Beijing, Shanghai, Seoul and Tokyo) have the most advanced public transportation system. Even in the US, cities with an acceptable mass transit tend to have decent levels of density.
