"Walkable"? What's next, special premium for breathable suburbs?
It wouldn't surprise me if out there in Finland you have breathable air in every community. But I'll bet there are many people who live with no easy walking access to certain services (hardware store, restaurant, library, food store, clothing store).
Short-distance walking access to essential services is by no means a necessity, even for car free people - I've met folks who live 10 miles from any kind of store and still only travel by walking,* and I've met folks who shop at locations 10 miles away and travel by bike, bus, or car.
*this is because they can't afford to travel by bike or public transit
