I'm pretty sure that a distinction is being made between low level chemical and high level behavioral influences.
I think the proponents of the safety of psychedelics are treating the influence as if it were comparable to seeing a movie or reading a book - something that doesn't really damage your brain physically.
Given that things like PTSD can be caused exclusively by psychological influences, and they appear to be at times comparable in effect to direct neurological damage, I'm not convinced that there is any sort of bright line distinction between these two effects.
I am not a professional in this field. Perhaps neurochemists feel differently.
