In the evolutionary struggle, I'd say all the fame and gorgeous abs haven't created Ramses-style success for Pitt. Academic reputation and billions of dollars do less for you than simply marrying a nice girl who likes babies would.
Yes, I think a lot of this focus on looks is just an exaggerated venting of sexual frustration. When you're not getting any, it can feel like the best thing in the world would be to become a Brad Pitt lookalike so you could have your pick and go out on some huge bacchanalic binge, but there's a reason a guy like Brad doesn't spend much of his time doing that sort of thing--it isn't all that satisfying or fulfilling.
In reality, once you are able to reach a base level of intimacy and satisfaction in one (or multiple) sexual relationship(s), how others perceive your looks in general stops mattering almost completely, and the fortunate truth is that achieving this satisfied state doesn't really require being some sort of Casanova, just moderately socially active, comfortable with yourself, and willing to put yourself out there occasionally. It may be slightly easier to be happy in this aspect of life as a very attractive person, but in the whole scheme of what it takes to be fulfilled, it's a fairly small advantage really.
..and looks stop mattering completely the moment people start speaking instead of looking and deciding weather or not speaking will be interesting.
How you look signals what sorts of conversation are likely to be possible or interesting. e.g. if you really like knitting, go talk to the person wearing the nice custom sweater.
