I do think dominance in the sense of assertive nonverbal communication can be helpful, even if being a caricature of manliness might not be. Covered a few studies on that in my last article.

Since this is in my wheelhouse:

'But something like the converse is probably true - are <20% of the men having ~80% of the sex, either by number of partners or by “number of times sex is had per time interval?” Yes, absolutely.'

As shown in 'the Chadopoly myth', 20% of both heterosexual men and women are responsible for a similar of their group's total sexual encounters (about 50% of past-year partners among 18-29s; for lifetime it varies within the age bracket), with no sign of men's skew having grown stronger. Therefore it doesn't constitute a 'Chadopoly' in the usually understood sense, as to the extent that these men are 'hoarding' women, there is a group of women 'hoarding' the same portion of men. Of course many of these encounters likely happen between those in the other group's 20%, though it's probably 5% or fewer that actually engage in 'promiscuity' as we typically imagine it.

This is also reflected in the STD data: heterosexual men and women's rates mirror each other's (Chlamydia is an exception likely due to detection bias, as screening disproportionately targets women as it's believed the effects are more damaging) and have been moving in tandem.

In terms of the supposed 20-40:80 historical male to female reproductive ratio, I'd question this being a justified inference. We know from the 1 in 17 anomaly that factors besides reproductive skew can affect the genetic record. One of these is female-biased migration, where women move to join their husband's group, increasing mitochondrial diversity across populations while Y-chromosomes remain more localised. This might be more common in agricultural societies, but I think is still more common than matrilocality among hunter gatherers. Men going on raids and killing rival men and absorbing their women could also leave a genetic mark even without formal patrilineal descent systems (which would have amplified the effect among agriculturalists). It doesn't have to be a constant culling of most men, it just needs to be so fewer male lineages ended up surviving.

Purifying selection on the Y-chromosome could also contribute, but that's more speculative.

Data from contemporary foragers doesn't just show typically low polygyny rates but also relatively minor differences in reproductive skew between men and women, so I don't think de facto polygyny through serial monogamy has a strong effect.

I'm sure your data is all good and there's a great case for why women want this. But I'm a man, and I don't have time to worry about what women want. I want more dominance and prestige because I enjoy having those things - they're a great experience - whether women want them or not.
