Mob-controlled porn DOES NOT eliminate coercion. Poor runaways who grow up as prostitutes and addicts who then move into porn litter porn, just as much as self-willed "free" actors do porn.
If you saw ten men gang rape a girl in public, would you masturbate to it or stop the rape?
Exactly my point. You did not solve the problem of coercion. The immorality is in the coercion (and that no consent is possible for minors), not in the pornography itself.
