We’re not supposed to take anything from it, it’s a simple legal liability thing. (And maybe actually mandated by law?) It’s like mandatory workplace trainings: they do almost nothing to prevent people from acting badly, but they let employers say “look we told our employers not to do this!!! it’s not our fault they did it anyway!!”
(More apt comparison is obviously alcohol commercials saying “please drink responsibly”)
Funny you say that as any level of alcohol consumption is bad for your body.
