I can respect this view 100%. And your rephrasing, "Should we recommend psilocybin treatment to depression patients more broadly," is in perfect sync with my thinking, and the right question to ask.

I would only add that it's extremely hard to know if something actually works. There are seriously some medications that people claim don't work, but objectively they are healthier, happier, more social, more active, and "better" on almost every objective measure. An example of this is when you really have a good match with venlafaxine for co-morbid panic disorder and depression.

Then there are drugs everybody claims are good for them, but they almost never are, especially in the long run. Basically, all of the benzo sleeping aids (in the context of chronic use).

So I can't and won't say you are not right. But I hope you permit me my goal of finding "objective" markers for saying "something works." Because, to quote Murderbot, "Humans are idiots!" (me included). And self-report is a notoriously unreliable measure.
