Also, I'd be curious to know how deep you believe your land ownership goes. Assuming your parcel of land is square, do you naively believe your ownership is an inverted pyramid with its apex at the center of the Earth?
No. That's known as the ad coelum doctrine. I own what I homestead. I haven't been to the center of the Earth. You can tunnel below my property and do whatever you want as long as it doesn't damage my land i.e. you can't cause me to cave in.
Humans create governments and grant governments authority, not the other way around. Property existed before government. Government is based on consent of the governed.
