Hard to say whether it's all about point scoring. Seems that the main point is to reinforce, or "affirm", their outward identity. "Whoah, look at me, I'm a housewife!". As with everything to do with such affirmation, it's skin-deep and plastic, even the "based" ones admit this. It's something to put on their character sheet so they can nudge the FEM stat closer to 20 later. The signalling is a call to action for the updootles, which are secondary external reinforcements. It's scaffolding, man.
Points for themselves, maybe, but external social points are a sort of byproduct (that ironicly they probably crave more than their own sense of self worth since everything seems to be external to these people, so perhaps I'm wrong).
