"There is the rational conviction that you can't own land because you didn't make the land."

Not particularly rational - you can't make land but you can buy it, inherit it, settle on it if uninhabited or conquer it by force of arms if not. I dare say most claims of ownership, if you trace them back far enough, depend on the last.

Besides, without ownership, what gives one particular person or group the (necessarily exclusive) right to farm a particular piece of land, build on it or mine it for coal or minerals?
