This is something you'll probably want to keep under your hat. I mean, I respect that your ideologically opposed to trophy girlfriends, but it doesn't really cancel out that you would actually like to just try it.
As for the original question, isn't it obvious why having a lovely lady is a status symbol? She's pretty, therefore she has high standards, which you meet, therefore you rule.
The flaw in that logic is the assumption that "pretty ladies have high standards".
And it's not even something I would want to try in practice... any girlfriend I would theoretically have I would have chosen predominantly due to personality (looks play a role but not as important). The personality is important because I want to be able to enjoy the activities I'm already engaged in regardless of relational status, just with said girlfriend.
