If that was not your intent, then perhaps in future you might say what you mean, rather than defending the vendors of false hope and perpetuating the extremely harmful myth that one can treat oneself.
As in this:
> patients themselves are often better informed than general MDs
No, that is a gross overgeneralisation and not true of any condition. A few patients may have slightly better information in one dimension of their condition than a GP. Presuming otherwise is foolhardy arrogance that misses the profound interconnectedness and subtle complexity of body systems. And this is especially the case with endocrine and immune systems.
Patients should be as informed as possible, yes, because this is always a benefit to one's treatment. Crossing the line into "I-know-better"-land is arrogance and idiocy.
