So I always thought that some things were obvious. For one thing, the male sex drive dwarfs the female one. Sex is something that women have and men want. Thus, a man must offer something to procure sex.

Some men ("alphas") possess intrinsic sociosexual status, and thus need offer nothing additional to procure sex.

Some men ("betas") lack intrinsic sociosexual status, and must offer additional resources to procure sex. This can take the form of prostitution, or repeatedly buying dinner/drinks and spending time with a woman.

I always thought all this was fairly obvious. But recently, I came across feminists who argued against this, stating something to the effect that sex is/ought to be something a man and a woman perform together, with no thought of exchange of value.

This sounded absurd and idealistic to me. I was wondering: how can people make this argument?
