If this isn't the "real" list, what's the real list of the world's biggest landowners? Would it also be more interesting to list by asset value instead of area basis? I think it's also possible to hold interests and control over assets (land) through companies and trusts without your family's name needing to show up on Top 100 lists. Certainly something I would be interested in doing if I was a billionaire. If a government is really effectively just a large corporation, are they effectively the real land owners? When you get down to it, what is land ownership besides the right to determine what's done on and with property? And are governments with military and enforcement bodies not the ultimate arbiters of who controls land, where disputes are ultimately resolved in some sort of conflict? Is land ownership a little bit more of a complicated subject?
