The Man Who Sold the Moon
A few American entrepreneurs, opposing these treaties, have taken the matter in their own hands and registered entire worlds as being their own property. Dennis Hope of the Lunar Embassy claims to be the owner of the Moon, and Gregory Nemitz of Orbital Development claims to own asteroid Eros, simply because they say they were the first. In addition, the Lunar Embassy is even selling off small pieces of the Moon to people around the world, stating that the buyers actually own their lands.
