This allows you to avoid the logical inconsistency in what counts as land value that most proponents commit, at the minor cost that nothing you say has any meaning. What happens when I try to respond to your new point of view and you reply that, actually, you mean something different by "money" than what is normally understood?
What would you think if you voted to establish a "land value tax" and the tax that was put in place comported with the ordinary definition, instead of yours?
Yes, that's my point. Your use is incompatible with the existing use. You are not responsible for the conventional use of the phrase "land value tax", but you certainly are responsible for presenting your own ideas under the same name and acting confused when people assume you're using the ordinary sense of the phrase.
Also, in blighted areas buying improved land may actually be discouraged by LVT because of demolition costs. Thus vacant land should be more valuable than improved land. Can you resolve the paradox?
What's the paradox?
Two identical pieces of land, both pay the same in taxes, one requires more work to improve it (as it needs a tear down first). So that piece of land will sell for a lower price than its neighbor.
Perhaps this isn't the value of the land as you would like to define it, but rather a way for local government to encourage land be put to more productive usage for everyone who lives or works nearby - without dictating exactly what that usage might be.
