Of course we can. You're perhaps thinking of ownership as being something more than a social construction, but that's all it is.

"Own" just means that we agree with other people that we have certain rights over some property - land, or whatever. That ownership is enforced to varying degrees by society. That's it.

Yep. The same fallacy would get you “we can’t own a candy bar because its component atoms originated in distant stars billions of years ago and will outlive our solar system”. Sorry, no, that’s my Kit Kat.

You can have your Kit Kat and eat it too? You must be thinking of Twix.

Sure we can. We made fences, guns, and governments to do exactly that. But it turns out these coordination and defensive devices sort of blow up in our hands. And come a huge hurricane, storm, flood, or fire, nature just laughs are our land surveys and continues unabated.
