Three miles is quite a long way though. From central Amsterdam, for example, it’s basically as far as the ring road and contains all the main parks
After my youngest graduated high school and we became empty nesters, we were in fact looking for that smaller place, walkable area, where we could easily get to gyms, restaurants, a park, etc.
We decided to change our entire city to a place in Florida with better weather and no state income taxes. Those places do exist in the US just like I am sure that most people who live in the EU don’t live in the idyllic places you describe.
