I was assuming that distinction to be true, and perhaps the machlokes M.B. and A.H. to be in which category to put nashim atzlanius.
I don’t think your position is at odds with the original quote from R’ Aron. I think its clear that he was stressing the primary role of women as being supportive. That certainly doesn’t address a women who’s circumstances are different, such as not having children r”l as you mentioned, and I don’t think it precludes there being individuals who have the ability to fill certain communal needs.
