This system of scientific gatekeeping and law enforcement is a direct projection of the barriers put in place between individuals and god by the catholic church. For millennia authorities have attempted to prevent people from having meaningful spiritual experiences directly, of their own accord, via access to substances that grow e.g. in their nearest cow fields.
In this way, your psychiatrist friend is simply the next iteration of a priest, and the portrayal of her patients as greedy fools only furthers this divide and pushes ever more people towards the other side of the law. I'll see you in _my_ cow field with a woven basket!
_edit_: think of it this way. An internal urge drives people to your friend in search of a meaningful experience. Your friend consults her good book and returns to them with information: no, you cannot have your meaningful experience.
