Agree with what you've said, but I think this post is also a lesson in how grifters try to "legitimize" their schemes. Look, this paper comes from "nih.gov". I mean, the National Institutes of Health is surely a reputable source! Point being it's not immediately apparent that pretty much anyone can get a case report published like this. If the report was instead posted a on Great Plains Laboratory blog, I think folks would have been more critical. Obscuring the origin of dubious reports is a classic technique that you see in Snopes entries all the time: eventually something gets repeated enough that it is taken as fact even if nobody can remember where it came from in the first place (e.g. "you should drink 8 glasses of water a day" is made up bullshit).
