Exactly. Although I think this is useful form of property, I also think there needs to be a way to value, recognize or sell the view or open space that people think they are getting when they buy a property. A beautiful view is worth something and somebody shouldn't be able to take it away arbitrarily. But you should also be able to sell your right to it so someone can build. And the same should apply to the expectation that a 100 story building will not be constructed next to your one story house. It's inevitable that a city will get denser as time goes on. If I had to choose between developers convincing city officials to let them build or their having to buy the rights to do so from property owners, I'd go with the latter. http://www.nytimes.com/2013/02/24/realestate/the-great-race-for-manhattan-air-rights.html http://www.nytimes.com/2013/02/24/realestate/the-great-race-...
