It's not the same people. When it comes to land, it's the cumulative wants and needs of regular people being matched against the cumulative offerings of greedy paperclip maximizers.

When it's furniture I have the option to make my own furniture, that's my BATNA if IKEA tries to screw me, and so IKEA has to be better than that if it wants to make any money. I don't have that option with land because it cannot be created or destroyed.
