That's exactly right. Land is not a commodity, in fact it is the absolute furthest thing from a commodity. Plots of land are different, and command different valuations based on location. It is not produced by anyone and has an unchanging supply. To call it a commodity is so completely backwards.

There are supply and demand dynamics in the land market. However much excess value you get from occupying a certain location on Earth, is how much people will be willing to pay for that. The demand will always be high as long as the value from the location is higher than the cost to occupy. This cost will soak up any advancements in society, which is why despite everything we have done to progress the state of man there is still a class of renters giving everything extra they make due to societal advancements to landowners.
