Drmiler,
of course Estonia is operating on a land value tax. The difference between what the article calls a "land value tax" and a "land tax" is that a land value tax taxes LAND ONLY and NOT IMPROVEMENTS, while a land tax would tax both.
This is still the very same difference between natural resource and produced good that I have been trying to explain for some time now.
The article makes that very clear:
"It [the tax] is based on market value of the land only (i.e., exclusive of improvements)."
Did I not make it totally and absolutely clear that I believe that it is a) possible to distinguish between the value of land (i.e. the natural resource) and the value of improvements (i.e. buildings, streets, mines etc.) and

that a tax scheme based on the distinction would be of advantage?
And the article says that Estonia does exactly that. So what exactly is your point now?
And I did read the text you quoted. That's why I specifically addressed it in my reply:
"OF COURSE land value tax is based on the market value of land. That's what "land value" means. The idea of the land value tax is to tax the value of the land, not the improvements. The value to tax is based on the market value of the land. It's not the same as the market value of the land though."
Did you not read that part of my reply? Or did you not make the connection between my remarks about the market value of land and the text you quoted which spoke of the same issue?
I'll try and explain it slowly.
1. The article speaks of a tax that targets land but not improvements of the land: "It [the tax] is based on market value of the land only (i.e., exclusive of improvements)."
2. The article says that the value of the land is determined using the market value of the land, as per your quote.
3. I spoke of a tax scheme in which natural resources (including land) would be taxed, and produced goods (like improvements) would not be taxed.
4. Again, the Estonian system taxes land (according to its value), but not improvements (i.e. produced goods located on it). That is why the article speaks of a "tax based on market value of the land only exclusive of improvements".
5. Bakerstreet claimed that such a tax scheme as I described would have horrible results, that I must have no clue at all if I am not able to see that, that it would only work if we all lived in tents, and that there is no distinction between man-made improvements and the natural resource "land".
6. He also claimed that evidence for his claim can easily be found in a news paper.
7. He did not provide such evidence.
8. But Estonia, a country which uses a tax system where land (the natural resource) is taxed and improvements (the produced objects located on it) are not, does not seem to suffer from these obvious results, which Bakerstreet refers to. The article does in fact claim that the tax has had a positive impact on the economy, because it prevents land from lying idle.
Where is the mistake?
