Structure and rules, fairly applied, hold our society together. They save us from chaos and injustice.
You can have structure and rules, but without fairness it doesn’t work. Just think Nazi Germany. You can have fairness, but without structure it fails. Woodstock may have been a few days of communal fun, but after a week or two the lack of organization (people crashing without paying, no food, etc.) it would have been an unbearable mess.
