If we are just putting our own ethical limit, for me it's 2.
-
Main residence, a traditional home like house, townhome, condo, whatever, but with full service like garbage hydro ect as is standard for the area.
-
Land, sort of what you are saying a country home, but it has to be zoned as such, not just another home in someone else's neighbourhood. So purpose built seasonal homes, or off-grid properties with an outhouse. Not somewhere most people would be comfortable living as their primary residence year round.
After that taxes should be extreme. And companies should not be able to purchase the main residence type homes. At all. Must be a person purchasing.
Oof that hurts.
I really, honestly hope you never make that kind of mistake, because while it would open your damn eyes, nobody deserves that.
"Haven't killed them yet!" Would be an awfully terrible thing to have rolling around in your head in the days, weeks, months and years after....
