It still doesn't follow from the premise that "society suppresses women to the benefit of men" that "any time an individual woman is suppressed, it is to the benefit of men". How do men even benefit from social taboos enforced my women against other women being geeky, or for that matter, slutty? That's probably the opposite of what would benefit men.

Society is more complicated than that. There are more forces swirling around than patriarchy. Any insular group will eventually enforce arbitrary social norms on each other, and since people tend to socialize with those of the same sex, both genders form insular groups in our society.
