Apparently the creators of the laws thought differently.I mean, I've been saying, "WOW!" to you this whole thread. I think your way is silly.
Actually there is a law that forces owners in certain areas around the airport to sell the air rights to the airport authority when they sell their property. Or the current owners can call the airport authority and they will cut them a check. (Last I knew of this was 15 years ago, they may be done with it now.).Do air rights extend indefinitely into space? No, that's not practical. I think it's about 500 ft. If I'm near enough to the airport where 500 ft matters, I'd be happy to rent them some of my airspace. But they don't get exclusive rights. They'll have to go around if I'm flying my drone.
If not “exclusive nor permanent” what kind of an enforceable agreement would it be?Similarly, I can see making a deal where the buyer grants use to the seller of parts of the rights that come with land ownership. But it wouldn't necessarily be exclusive nor permanent.
Also, I was told by a real estate attorney that when the farmer put the no pigs restriction in place, that after the farmers property changed owners the owner of the restricted property could petition in court to remove it and likely would win if the new owner did not object.
