Your overall thinking is similar to the one of Esther Vilar, The Manipulated Man. According to Vilar, both men and women have the same three wants:

A Self-preservation - you call it protection

B Procreation - you call it sex

C Caring for offspring - you call it wanting children

Vilar then explains quite logically how women control their sexuality to force men into the role of the protective provider controlled by her. In other words, women control B to optimize A. In Vilar's philosophy, one would need to adjust two points to your initial axiom of basic wants:

1. In a natural, unsocialized form, women and men alike want to reproduce in order to outlive their own finiteness.

2. To gain protection, women don't subordinate wanting children but it is the sex drive they subordinate.

By adding 1. and 2. the phenomena you describe in your article, e.g. women being jealous of the protection being offered with nothing in return to children, can be described more elegantly.

To what extent would you agree?
