I don't refute anything you say, it just sounded like OP thought something like "well in Europe they all just live in their inherited ancestral homes" where as the reality is that people mostly rent, and of those that own a lot of people bought new homes via parental support (which is still not the same as the supposedly hobbit-esque family domicile that passed from one generation to the next for the last 400 years we all supposedly live in).
I'm sure there really are centuries old farmhouses in Tyrol that really work like OP mentioned, but it's not the common way for Europeans to live.
