Why...?

Because why bother saying anything if you aren't going to say anything? Offering correct information gives the other person a chance to correct and improve. Just saying 'WRONG!' is just a slap in the face that only serves to let you feel superior, masturbatory pretense.

As for the rest, those are all clearly issues, but none of them are of a sort where handling the one I raised and handling them are mutually exclusive. And at least the second item is actually a following point from the one I mentioned. People being tricked into thinking LLMs are capable of thought contributes to the thought by decision-makers that people can simply be replaced. Viewing the systems as intelligent is a big part of what makes people trust them enough to blindly accept biases in the results. Ideally, I'd say AI should be kept purely in the realm of research until it's developed enough for isolated use as a tool but good luck getting that to happen. Post hoc adjustments are probably the best we can hope for and my little suggestion is a fun way to at least try to mitigate some of the effects. It's certainly more reasonably likely to address some element of the issues than just saying 'WRONG!'

The fun part is, while the issues you mentioned all have the possibility of creating broad, hard to define harm if left unchecked, there are already examples of direct harm coming from people treating LLM outputs as meaningful.
