I think JustAGeek did mean that. I also took it to mean, however, being up front about what she wanted and setting explicit expectations, all of which tends to come at a cost for women (part of the reason so few of them do it). And yes, men can opt out in the way you described (and I think that's a better reading of what she meant), and you're right, that's not really a viable option for them if they want to be with a person. Women opting out of their social position increases the likelihood of them finding a partner; men opting out of their social position dramatically decreases their likelihood of finding a partner.
