Not that "owning a space shouldn't exist," but we should clarify and question "owning a space," because we casually and colloquially believe/accept "property" incorrectly.
Our minds just generally go to the 3 year old's conception of property, "Its mine and I can do whatever I want."
But, of course, no. "Property" for grownups is a jumble of rights AND responsibilities.
It's good to question those, especially when it gets to what might be absurdities, e.g. Ted Turner owning a literal U.S. state's worth of land.
