question Can you buy and flip celebrity's names?

[abstractdomainer]

I have seen some celebrity names sell for 4 or 5 figures. And this seems to be a debatable questions:
Is it an infringement to sell a celebrity's name or is it ok to sell, since it may not be trademarked?

Two questions here:
1) Is it legal?
2) If it is legal, is it ethical?

More on this?
What about normal names of people, which could also be a part of a celebrity.
Say Ellen(dot)com. Is that okay to own and sell, even if your name is not Ellen.

Well, this is a poor example of only first name. What about a popular full name?
