> Property is granted by governments. Why? Because it's a useful abstraction. This is where that 'broad intellectual foundation' comes in. You may think that it is, sure, but why? Not everyone does, and there's a whole lot of philosophical discussion on this very topic. Our conception of 'private property' has only been around ~200 years, and humanity's been around just a bit more than that.
So you think private property was invented in 1813? I guess the War of 1812 was more important than anyone could have dreamed at the time? You really need to read more. Like... a lot more.
(the ~200 figure comes from the Inclosure acts, which, as Wikipedia says, "the majority were passed between 1750 and 1860". Even that is obviously a rough time period, and only one of many significant historical events. Even if we take Locke's birthday, 29 August 1632, as the birth of private property in the current sense, that's still roughly 380 years ago, which is still pretty new as far as human history goes.)
