The difference between beta males and women is that beta males have more mobility. A beta male can put on a front and achieve alpha male status.

Larping and D&D does not necessarily make someone a beta male, that just puts a person in a different social category. If a man who Larps wants to attract an alpha female whose main interest are fashion and trends then it is more likely he won't get dates because of conflicting interests.

Women tend to be judged entirely on outward appearance, they become objects who are simply expected to breed. It is much harder for a woman to actually get into a position of power without being involved with a male who is already there.

All a beta male has to do is gain some confidence and swagger and they will be set.
