There’s no lines to read between.

I didn’t say women need to exclusively be mothers, I said that is where they need to focus for the extended order to most benefit. For them to be good mothers they’re going to need to have other interests which is no different to men who should be the breadwinners but will not be well-rounded fathers if they have nothing outside of their work - one-dimensional people do not make good parents.

But the idea that people can do multiple things and excel at each is nonsense.

We should be moving to a world of hyperfocus where each of us devotes the majority of our productivity to what we are best at (outside interests should be leisure) and realistically we need women to be best at raising the next generation to extend that rather than deferring motherhood or palming it off to the state as that is what perpetuates the very system you identify as broken.
