Yeah, it's a kind of zoning. But a quite strict one. And one that's not easily abused.

For instance, if you're tax based in Oslo, you would have to "move" to buy a family home in my city and use it as a cabin. And that move on paper has implications. Where you can vote, where your children can go to kindergarten or school, how you're taxed etc. So people don't do it.
