Also, ChatGPT has allowed people to get their rare conditions diagnosed, quite possibly saving lives. Is it an unmitigated good because it did that?
"As a chatbot, I can not inform you how to invert a binary tree as it can possibly be used to create software that is dangerous and morally wrong"
I apologize for the slippery slope but I think it does show that the line can be arbitrary. And if gone too far it makes the chatbot practically useless.
Have a look here:

And here:
https://www.amazon.com/s?k=herbal+medicine Unlike homeopathy, some of these are probably actually effective to some degree, but many are bunk, if not outright dangerous. Recall that Steve Jobs opted for "herbal medicine" rather than getting cancer surgery.
So yeah, I'm going to have to say this is a straw man.
"Dr. Google" has been around for quite a while now, with much of the same criticism. Notably, the whole ivermectin debate took place without the help of AI. On the other hand, patient education is a big part of improving outcomes.
Anecdotally, "improve access to information" and "improve literacy" seem to appear far more frequently than calls to ban Google from displaying results about healthcare or restricting access to only licensed professionals - at least in content from healthcare professionals and organizations.
An important thing you can do to help is to identify these people in your life and tell them not to blindly trust what the computer tells them, because sometimes the computer is wrong. You'll be doing them an invaluable service, even if they think you're being a condescending jerk.
