Mmmno, I wouldn't go that far in what you're concerned.

dysfunctional people are plentiful (and glorified) and then at the same time have the argument in front of me that clubbing for sex is actually turning out very healthy people
I still believe you're just not addressing the right issue i.e. those people have not become dysfunctional because of their hedonism, but rather due to their IQ, education and values, or lack thereof, which in turn led them to a depraved life, using sex to assuage their existential anxieties.
And I'd side with you on the somewhat disgusting side of clubbing for sex. Personally, I can't help connecting my visits to certain clubs with strolls to the Zoo.
