Your Toyota is more of a commodity. There are millions out there that are functionally identical, and millions more can be made. A given piece of real estate with proximity to a major city is very different in this sense, as there are only so many plots of land like it.
A given piece of real estate is a monopoly in the same way that a given individual car is.
There are a large number of pieces of real estate with proximity to any major city. They may all be controlled by some monopoly, depending on local laws etc, but typically they don't.
It's true that it's easier to make new cars than new land, but that does not in itself make the buying and selling of these things all that different. Note that the making of Toyotas actually is a monopoly.
If we're arguing based on time, we might as well say that the tides are changing the amount of land available in any given geographical region. The only difference is scale (i.e. Toyota won't be putting out new vehicles forever)
Only in the same sense that I have a monopoly on my Toyota.
