But seriously, if you don't like Freud, you're going to have to come up with a better response than just saying he's a kook; we all know he's a kook!
A) Talk therapy was the mode invented by Freud and is still the dominant modality of psychotherapy today, and
B) While you didn't mention it but, at the time, Cocaine was in common use as a near magical local anaesthetic and from it we derive procaine, lidocaine, any drug ending in -caine, which you certainly have been administered before, and
C)If all we have in our psychological and social lives are narratives, and the narratives bind us into certain patterns which we don't even realize we are following, then the counter to that cannot be another narrative which equally obscures its reproductive capacity (ie "the data"). Freud created stories that untied themselves at their roots, that put patients, not to mention regular people, ill at ease. Even sex with siblings is less taboo, certainly less universally taboo, than sex with one's parents, even if the latter is more genetically troublesome--is this an accident? The stories got to things at their base level, which was impossible by any other means. They might be a bit weird, but they force you to think, maybe even to act differently under the right circumstances (those of treatment), and the latter is what we'd call medical care, no?
