Population density relative to population. The US is not dense. There are legitimately strategies that will not work for us given some of our "large population centers" are actually pretty tiny when considering hpw developed we are. This is also why the US has 3rd world problems like issues getting water and electricity to some citizens. The population density in some states can drop very very low and we have a lot of people on those low density areas. It becomes a horrible last mile problem.

Honestly, I'd like to hear from Canadas and Australians about the rural experience. They have the same density problems and I think their solutions are nore relevant. That said, I'm not really a fan of the outcomes from Canada, so who knows maybe high population, low density is just a bad hand for a country in this context.
