Karl Marx criticizes rights for reducing man to individualistic, egoistical desires and interests

Karl Marx criticizes rights for reducing man to individualistic, egoistical desires and interests. Martha Nussbaum claims to take inspiration in part from Marx's view that politics and economics should be organized to aid the "the human being in need of a totality of human life-activities—the man in whom his own realization exists as an inner necessity, as need." How might Nussbaum engage with and possibly refute Marx's objection to rights, given their shared concern with human flourishing? I need this as detailed as possible please!
