A lot of people in Europe have lived like this for generations.
They just don’t have as much “stuff” as we do.
The biggest downside for me would be the lack of yard work. I’m a bit like Hank Hill, I do enjoy mowing and such.
I do think Americans are a bit too spoiled when it comes to apts/homes. Not everyone needs a 3 bedroom, 8 1/2 bath apt or house.

Our concepts of personal space are larger here as well. People here are a lot louder overall too. More obnoxious and not caring about disrupting others.
