Not exactly a land value tax but zero tax Monaco is funded basically by the state owning and renting out property. I think similar in Dubai.

There are some practical advantages - if you've got a patch of dessert and charge tax on it you only can get so much but if you develop a luxury apartment complex on said land and rent them out you can get rather more. The state has an advantage over private developers as it can grant itself permission to build whatever.

I sometimes think you could do something like that in places like London - the state build lux accom to replace tax revenue rather than letting private developers clean up.

Kinda the opposite thing is happening right now in Germany. When introduced in 1968, the value added tax was 10%. Now it's 19%. Similarly, it was free for trucks to use the German highways. Now they have to pay fees. Only recently they expanded that to the federal roads as well (Bundesstraßen). As for the land, generally the federal government sells most of it to developers instead of developing it themselves (or letting developers develop and then charge rent on the land).

Sounds like you have some terrible nightmares!
