The p4p scene isn't a cure for the disease, it's just a logical consequence, a symptom even. That is the implication of the poster. (Not mine, and I think not that of most others here.)
You don't keep taking penicillin after the syphillis is gone and you don't take it if you don't have the disease, just for fun. In fact, if the disease doesn't exist there is no need for penicillin at all, in fact. The whole situation is fucked up.
I don't know anything about the poster's inner thoughts on this industry and the people involved. Either he has a fucked up view of all of us, his logic is faulty, or his communication skills failed him here. That's all I know or need to know.
