A population under 10k is closer to a village than a city. There are towns with a population of 5k that do indeed have their own clinics and even their own train stations as long as they are not located on the side or the top of a mountain, though it is extremely rare for a mountaintop settlement to have a population greater than 3k.

It is honestly baffling to see that people can not fathom that urban sprawl can take shape without suburbanization. You can have houses concentrated into small splotches of land and those are chained together by a singular road and railway. Everything around that is just farmland. That’s just how villages look like in Europe.

All you’d have to do is do away with american zoning regulations and use european urban design principles instead. The market itself is impatiently waiting for that change in policy to happen.

Even cities below a population of 100k have their own hospital and dozens of doctor’s offices all within a ten minute walking distance from each other.

They roll their own crypto which is a big no-no in information security.
