Capitalism has _everything_ to do with this as while the _amount_ of land may not be growing, the economic system does _nothing_ to cap the price of this essential commodity. The only cap on the price of land is the amount someone is willing to pay for it.

To say that the advantages of location are not capital (or equivalent to capital) is just ignorant. There are plenty of pieces of land that act just like capital - access to natural resources, access to a coastline, fertile for farming, or in a location where a toll road or similar could be employed.

It becomes very difficult for someone to build and own a sapphire mine if they don't have the capital to buy the land that has the sapphires in it!
