The funny thing is that in Capitalism, something is your property by virtue of it representing a piece of your life. You own your life, therefore you own what has been created with your life-time and life-energy.
But, here's the catch, nobody created "land".
I must have missed the point where someon can capitalisticaly claim land as theirs that does not involve a huge act of government somewhere inbetween, probably terminating to a feudal King and an army of thieves, thugs and murderers.
So its a bit of a funny point, but in "proper" capitalism, you can own a sculpture, because you own the energy you invested in shaping it, you can own bottled water, because you own the act of bottling it, you can own a house obviously, but you can't own land.
Those who say so, are incidentially called Geolibertarians. Who in fact say that there should not be a single tax in existance, but the tax to the community for the right to exclude others from a piece of land. No one might be using that name but its not an idea that didn't exist since Thomas Paine's time, who wrote:
"Men did not make the earth. It is the value of the improvements only, and not the earth itself, that is individual property. Every proprietor owes to the community a ground rent for the land which he holds."
The only case of properly "capitalistically" created land I can think of, are the palm islands in Dubai.
