What I find interesting about comments like this is how revelatory they are of the worldview of the people writing them. It's always interesting to see which facts about the primal human experience are left out when this kind of thing is discussed.
For example, I'm betting you're a male who likes women who's between the age of 20 and 45 and likely doesn't have children (I'm pretty sure on male between 20 and 45, but children could go either way).
Consider the assumptions present in: "Of course this also begs the question of what happens to a woman when she gets old and ugly? Where does she get her power from? She gets it from her man."
The assumption there being the only reason a man would protect a woman is because she's pretty and she's having sex with them, likely because the sexual relationship is the main way you're looking at women at this point in your life. Even if we assume women can only derive power from male proximity in nature, there's an obvious alternative answer to where she would derive power from: Her sons and grandsons. If she lives through her childbearing years, a woman in nature is far more likely to live to old age than her male mate: She has better resistance to famine, a better immune system, and if we assume the rigid gender role evo-psych of men = hunters and women = gatherers, she also engages in far less physically risky activities. Even if 'her man' is alive, the odds of him being crippled or simply unable to protect her from younger, fitter men are high. A 35 year old son or 18 year old grandson is far more valuable for protection, and far more stable: a man is always her son/grandson, whereas if we're assuming the red pillish evo-psych is true, 'her man' probably has wandering eyes and would like a younger woman and therefore should not be counted on to stick around once she dares to have wrinkles and saggy breasts. Additionally, a man who doesn't protect his mother is failing at one of the basic tests of belonging to a human tribe: Basic reciprocity. If a man won't give to the one person who took care of him when she gained nothing/he was at his most vulnerable, then how can his fellow hunters (who he's less attached to) trust that he'll reciprocate when they help him? This assumption also outright dismisses the bonds between say, a brother and a sister. Do you think most men wouldn't protect their sisters because they're not sex objects?
Older women are also far more able to keep contributing to the tribe than older men if we adhere to this strictly gendered idea of primitive humans. They can care for children while women in their prime gather, they can rear children whose mothers have died (and this is common due to the fatality rate of childbirth), they can take care of the sick, etc. A man who can't keep up with his male duties is far less useful - a man who is over 60 and has 60-80% of the speed and strength of his fellows, or a bad limb, or sensory impairments, is far less able to hunt than a woman over 60 is to caretake. They're more likely to live longer and therefore a better repository of historical knowledge.
Idk, I just always find it interesting which physiological and psychological aspects of humanity are ignored or unmentioned whenever someone is making some kind of argument about primal gender roles.
