But isn't that specifically the challenge, in defining what's a "clear and present danger to others?"

I agree that many things do normalize over time. We create informal rules on how to interact, embedded within morals, ethics, or just expectations of how one should behave in a society. I also think sometimes rules don't informally coalesce, that we don't always resolve conflict without outside guidance and more formal negotiation.

From my (cursory) understanding of at least German law, while there may not be a speed limit on some roads, those roads often have very strict laws about passing on the right, and one might get their licensed removed for doing so.
