Good hypothesis, but from a psychology standpoint each one of us is unique and thus has its own peculiar things. A man with a bright mind that was capable of creating Bitcoin is certainly special like every one of us. 
My point is that not everybody has a need for attention and fame. There are people who just want to do meaningful things and not be the center of attention. Just imagine the amount of publicity and renown he would get if he revealed himself. One needs to think deeply about his lifestyle when making such decisions.
While you are correct and people have different motivations we also need to consider that satoshi was afraid to be put into jail, after all do you really think that if we knew who satoshi was that he will still be free and not in jail? Governments would have tried to accuse him of all kind of crimes, satoshi knew this and decided to never reveal his identity, also if we knew who satoshi was governments could have tried to destroy bitcoin by using character assassination techniques and try to discourage people from adopting bitcoin that way.
