This has been a big part of the shift in recent years. It used to be that if people said things like this, they couldn't hide behind, and almost no one would grant them, that they actually believe it. Because it doesn't matter if someone believes the Earth is flat. It isn't. Of course the big problem here is that someone talking about flat Earth would mostly get dismissed because scientists disagree, know that it's false.
But here the problem is unresolved, there are no real experts, only authorities. Mostly by choice, but still. So the arguments are all forms of logical fallacies hiding behind the appeal to authority fallacy. Some decades ago, most physicians paid no attention to this stuff. Alternative medicine was fully independent of scientific medicine. No longer, now they strongly overlap, and that completely breaks relying on experts. The beams have crossed, and the giant marshmallow monster is rampaging around.
I don't think it's caused by the thing that started roughly 10 years ago. The one I won't mention because of politics. I think instead it was a consequence of that natural shift. It just turns out that medicine is not only not immune to this, for historical and institutional reasons, it's especially susceptible to it, while for the most part absolutely certain it is completely beyond falling for it.
Humans love magic. In the end this is what it's all about. This is healing magic. It's completely mediocre healing magic, but it's too alluring to ignore. It's also way too convenient for the privatization of problems and the socialization of losses they incur.
