Yes! Diversity. All systems have failure modes (current fav: utility monsters). By combining multiple systems, you limit the severity of a failure of any one system. All participating systems must be in a failure mode for the overall systems to be in a failure mode. If the Supreme Court were elected, it would suffer from basically the same failure modes as other elected offices, and would be able to provide a systemic durability against those failure modes.
