That makes sense because it provides a release valve for new companies to come in and demonopolize unexploited properties that have become stale and are taking up space in the market. Actual property tax works the same way (especially in commercial districts), though I don't think it's fair in that situation because you're talking about literal property which they tell us we own, not rent from the government.

(I don't know the technical name but other types of intangible resources that have this quality are shelf space in stores - which the store owner regulates - and the public airwaves.)
