Simple - there is no real lasting money in psylocibin as most people really only need 2 or 3 good sessions.
Whereas adderall is not technically addictive, but if you can function on it, you do become dependent on it.
You also really don't need it to become a prescription, shrooms just need to get legalized. The risks that come from overuse are far and few in between to the point where normal over the counter meds carry much more danger in abuse than shrooms do.
I don't think I've ever heard someone claim that Adderall isn't addictive.
> use of amphetamines and stimulants such as Adderall can result in tolerance and physiological dependence and can lead to the development of a substance use disorder. Misuse of prescription stimulants such as Adderall for any reason (e.g., to improve academic performance, reduce the effects of other drugs, etc.) is associated with both substance use disorders and use of other substances.

Through direct experience, I do not think 2 or 3 good sessions and you're done is really true. Maybe with experience even that goes - you learned what you needed to learn and there's nothing more to it.
But IMHO psilocin is a strong anti-inflammatory which may in and of itself be some (not all) of the mechanism for alleviating depression (the link between inflammation and depression is strong). That will almost never be lasting.
So we may be in the case where the real breakthroughs are, as you say, in the first two or three sessions. I think most people who took mushrooms out of desperation would agree with that - by the end of the third session many of the things they needed to accept are, in fact, front of mind for awhile. But ongoing maintenance is probably useful.
Has nothing to do with being a one shot solution vs subscription.
Even economically the conspiracy theory against one shot cures makes no sense. As your shitty subscription solutions all go generic, I enter the market with my low risk one shot cure and eat all of your lunch.
