Yeah I agree with you 100%. it's interesting folks immediately taking the experience and result at face value when we understand so little about what's happening, even without psychedelics is most cases.
In the referenced anecdote it could be as simple as an excuse needed for someone who's been thinking about it for years. Though maybe that's enough to be a benefit
Anyway I like your example and look forward to what is learned about using psychedelics to help people :)
