Being Hawaii though, I don't think he will get a private beach, though :)
There is something I find very odd and unsettling about Zuckerberg. One day I think we will yet rue making him such a success.
With that in mind, I feel that the issue of privacy with respect to one's home/private property is very different. With this, Zuckerberg is likely thinking about the physical safety of himself and his family.
I'd be curious to hear more about what you find unsettling about him.
