Oh? I have an intrinsic right to the land that I currently own, the car in my driveway, and the computer I'm typing this on? How did that intrinsic right derive? And why don't I have an intrinsic right to, say, the land of the entire continent of North America?

Property rights are entirely a social construct. They are not intrinsic; they are created and granted solely via the formalizations of that social contract in the form of the state.
