Earlier quoted context omitted.
I think it is clear that the parent is using home-ownership to include land-ownership.
Don’t know how it is in most of Europe, but I think that, in the UK, you don’t actually own the land your house sits on; Lord Such-and-Such owns it, and collects rent from you. In the US, we own the land, and that is usually the real value. I’m the proud owner of a 0.125-acre New York postage stamp. It’s in a fairly affluent area, so is fairly valuable. In Wyoming, they’d laugh at it. I think Japan is similar.
How much do you really own?
