How so? All "rights" are manufactured by humans. We would like to say that "life, liberty, and the pursuit of happiness" are "natural rights", but they're not: a bunch of people just agree that they should be, so they are. (And imperfectly, at that! We wouldn't have capital punishment or prisons if we actually believed in these rights.)

And if we recognized "physically being present before others" as a natural right, I imagine the Native Americans would have a much better situation than they do. Thinking that's a right for some but not for others is the height of hypocrisy, but that seems to be what a lot of incumbent property owners here seem to believe.
