tell her that at one time women who could no longer give birth or provide for the family were considered worthless. at this point in time what does she think her value would be in a society that believes women are to be used as breeding stock and slave labor?

regardless of what she says follow up with, why does she believe she has value when clearly she’s past her prime and can no longer provide children or support the family?

fight fire with fire. if she wants to follow archaic social behaviors throw them back in her face.
