This is true in high-density to medium-high density situations, like most of the east coast. I challenge you to describe such a system that works for eastern Montana. The US is very large, and a lot of important things are done in places where the density is insufficient to support a greyhound route, let alone high speed rail. Not everyone lives in a city, and if they did the nation would cease to function.
