I don’t understand what you’re trying to say here. If the value of your property goes up you pay more in taxes. Of course property taxes have something to do with the gain or loss in the value of the property. The relationship is in fact direct and unambiguous. (I think people are just getting caught up on the article's use of the word, "income," which was indeed well-poisoning from the start.)
