It's because if a woman is not completely dependent on them to able to survive, they will NOT stay with them. They will not be near them, they will not talk to them and just disassociate with them in every way possible. And if not that, they will just be used on for all the resources and left alone anyway. So being with a woman who is entirely dependent on you is a lose-lose situation anyway!

Edit: This also brings up the other very obvious reason for this is because women are the center of their world. They love to say how beta males make women their everything in thier world, and thier why which is why they always fail with women, yet these guys are constantly whining about women being independent, women having sex with who ever, and whenever they want. And the reason why they want this is because they know that if women are like this it SEVERELY HURTS there sexual prospects (watch any one of Walter Fate's videos on Incels, it explains this PERFECTLY). Which is why I personally I hold the belief that a lot of Hardcore red pillars most likely don't even much talk to women, much less have sex with women on a regular basis, given that they have this way of thinking about women. So to be the only feasible way they could be doing this is probably through hookups on dating sites, or prostitutes. (P.S. Fuck you Hafeez from the Roommates)
