Fantastic cultural divide. This is one of the reasons why I read HN. Most of Europe is more or less walkable - one reason is that the largest urban centers predate cars, but intentional design AF (anno ford) is also a factor. I can bike or walk everywhere, and the only reason I have a car is that it makes grocery shopping much, much easier. I am not very green or anything, I just like to keep things simple. You can c…
The walkability comes at the cost of tiny housing though. Like here in Stockholm even 60m2 is getting very pricy (~350-450k USD).

You might have your correlation/causation things mixed up. Walkability means higher quality of life, which means higher demand thus higher prices. In turn, as real estate prices go up, real estate developers are pressured to provide more houses from a limited construction area, thus this means shrinking apartment sizes.
Offering smaller apartments also has the advantage of increasing price per unit of area, while keeping selling prices within reach of the market segment you're targeting, i.e., you might not afford 1M for a house with 200m² but you might afford 500m for a house with 100m².
