What do you get somebody who has everything?
Well check this out...
You can actually buy acreage on the moon through The Lunar Registry, "Earth's leading lunar real estate agency."
Based on The Outer Space Treaty, no country can own a celestial resource such as the moon, planet, or asteroid, but this doesn't preclude private entities and individuals from purchasing a "lunar land claim."
The Space Settlement Institute, which "promotes the human colonization and settlement of outer space" is lobbying for the U.S. to recognize these space land claims (PopSci).
According to their website, when you purchase real estate through the lunar registry, "your property ownership is permanently registered by the International Lunar Lands Registry in its annual publication, which is copyrighted and deposited in the United States Library of Congress and with international patent and trademark offices."
You can view available properties here, from the Sea of Vapors ("moon on a budget" for $18.95 per acre--near Crater Manilius) to Lake of Dreams ("most popular" for $34.25 per acre and a special "Sweathearts package with 2 acres side-by-side).
Properties can be viewed at The Full Moon Atlas through The Luna Society.
I found Lake of Dreams by its reference in sector B-4, although I couldn't really tell from the atlas whether this was a place that I'd like to settle down or not.
In real estate, they alway say "location, location, location"--when you're buying on the moon, who the heck knows? ;-)
