Those are all valid points, but aren't those all (edit: mostly) examples of women being forced to work instead of choosing to work? Also I'd say those are exceptions to the rule, not the norm. If anything I'd say you bolstered the top comment's argument (I do not know your stance and am not trying to be combative).
Aren't majority of men forced to work instead of choosing by that definition? These are examples women people living real lives. Wast populations. There was such a thing as idle lifestyle of aristocracy in places where the situation allowed that to male aristocrats. Spending most of their time socializing with each other.
Also, overall they easily make majority of population. Combination of family farms, non-aristocracy, poor people, war situations, dangerous or far away occupations for males, pre-industrial are largely majority of "centuries if not millenia". Can I add former slaves who would be significant part of population here?
The "we expect the half of population to be mostly idle and mostly unused" is unnatural exceptional situation. And in case of muslim countries considerable physical violence is used to keep it that way.
When you talk about what was happening and was feasible for centuries, you cant skip over such was populations. They did not had power, had less control over own lives, but they did existed and count.
Also, most of those feminists marches were middle class or rich women. Poor women worked already, they however had sucky jobs and had completely different needs. Turns out that when women are actually in that supposedly great optimal situation, they want to get out, significant percentage is discontent and unhappy.
