> Property rights are the foundation of civil society.

It's one a set of rights generally considered essential, i. e. "human rights". But among those it doesn't seem to be considered very special. The UN charter of human rights (written in no small part by the US) finds 16 other rights to list before it gets around to property: http://www.un.org/en/universal-declaration-human-rights.

But anyway, I fail to see how even utmost reverence for the centrality of property would change anything about this:

People inherit stuff. They leave it to multiple children. Therefore it gets split up. To force any of them to sell against their will is obviously infringing property rights – not that it's not possibly justified, but it seems pretty clearly on the side of a less strict application of "property rights".

And "when everyone owns something, no one owns it" is just wrong-ish, at least in the intended sense of neglect and uselessness. The Statue of Liberty is owned by everyone and no one, as are the airwaves, most of the Rocky Mountains and the works of Shakespeare. All of them seem to be doing fine.
