Again, that's missing the point of drug regulation. There's plenty of substances even more dangerous than Tylenol, but aren't banned. "Drugs" are banned due to a combination of (perceived) harm to user/society, potential for abuse, as well as toxicity. That's why there's plenty of substances more toxic than Tylenol, but aren't banned.

But that's missing the point of the discussion. Yes things are banned based on perceived harm instead of actual danger, that's the point of the discussion.
