If it “makes me feel better”, fine.

If it “makes it so I’m not contagious and won’t give you Covid”, no.

My mom died of cancer a few months ago because she was convinced that a combination of sunlight's natural vibrational frequency and some expensive "medical" herbal teas would cure her. Placebos affect people, but if you let them believe that they're an alternative to actual science and medicine, then they'll use them as such.

you really haven't thought this through, have you?

Not only does this encourage scammers to scam people, which is itself obviously bad, but it also means that some people will buy these things instead of getting actual treatment.

I feel like with all this placebo stuff you get like 10% increase in perceived well-being vs. a good 10% of the population just going full woo woo about this stuff

Selling people fake remedies is always going to be to the detriment of real remedies unless they are targeted exclusively at conditions for which there are no real remedies.

Furthermore, the real issue isn't about "letting people have their crystals", it's about letting people sell fake remedies, something that should be banned unconditionally. Profiting off of pretending to help people while not helping them is socially malignant.

OP is phrased in terms of attacking consumers because the poster is an idiot, as made evident by their absurd and pandering rhetorical tact.
