I really don't understand this argument. Land taxes are supposed to pay for the various services in the area (schools, roads, etc). You don't pay your fair share and be done, you pay every year because those services cost money every year. If, at some point, you can no longer afford those costs (excluding those situations where social welfare safety nets are supposed to help), you move somewhere else. You don't get to keep taking advantage those services without paying for them just because you've been there for a long time.
