The parental grief is not even subconsciously about reproductive value - otherwise it would update for Canadian reproductive value instead of !Kung reproductive value. ... Parents do not care about children for the sake of their reproductive contribution. Parents care about children for their own sake.

This just doesn't follow. Just because there is one feature that isn't taken into account and updated optimally in grief intensity doesn't imply that nothing else is taken into account but "the childrens' own sake", whatever that means.
