If Tesla hires a bunch of people to take care of the land. Then the people who take care of the land would own the land. And they may say they are taking care of it for Tesla, but that is trivial information. The one who takes care of it owns it.

And if it is not being taken care of, then it is not owned. Now matter how big/powerful the corporation is.

Especially The US govern-cement, who claims they own most of south-west America.

Billy Gates bought a lot of farmland… that is mined out. Useless. Worthless. Unless someone goes and revitalizes it. And the person who revitalizes it, will be the owner in the future.
