This is incredibly naïve. Social norms change, often quite quickly and in unexpected ways. You could have a near future where posting nudes is 100% normal, then 10 years after that it becomes quite taboo again. The problem is that the internet never forgets. The harm caused is that an action you take that is socially normative, legal, and accepted today, may not be in the future, and if that action is documented online, it will inevitably be judged by an ever-changing set of standards and morals as time marches on.
