You keep saying things like this. You seem to have this notion that having title to some land means that you have immunity from the rest of the Universe while within the boundaries of your property line. You have this sense that a property deed (which is a piece of paper and perhaps a digital record on file in a county recorder's office) confers upon you some fundamental physical law.

That is where you are wrong. Land ownership is nothing more than a social contract that does not necessarily give you the complete set of rights that you believe it does. To put it bluntly, the neurons inside your head have one interpretation of what it means to own property in the United States, and the neurons inside other people's heads quite possibly all have slightly different interpretations of it. Your best bet is to see what the neurons inside a judge's head believe.

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?

The point is, you don't really know what land ownership is. You only think you do, based on your ideal interpretation of it.
