You know maybe it would hark back to the garden of Eden if people were to lose their inhibitions a bit more. Could it be that the simple act of wearing clothes set us on the path to civilization? Adam and Eve, once they had taken of the Tree* and people started wearing clothes they got kicked out of the garden of Eden. Eventually out of wearing clothes comes the the family, the basic unit of civilization. They took us from packs to family units without which civilization would not be possible. Even though all that's great, I still see some ways they had it good in a more day to day time of human existence.
