To recap:<p>[1] Random person on Hacker News personally &quot;knows&quot; a billionaire.<p>[2] Billionaire renounced U.S. citizenship without having to realize any significant capitals gains.<p>[3] Billionaire doesn&#x27;t own a car.  He just spends his time touring Africa, solving AIDS or malaria like Bono or Bill Gates.<p>[4] Billionaire has a secret lair, from which he dresses up in a costume and fights crime by night.<p>I could be making some of these up.  I started to have serious doubts right at [1], and completely got off the train by [2].
