That's for people who have addictions. If that the case we should ban everything a person can be addicted to.
In my opinion society is more dangerous than porn. Telling boys not to cry or they look like a sissy, boys will be boys, it's a man's world, girls can't play sports, dress like a lady, victim blaming and shaming. Many more, watching people fuck is not a big deal. Can it be addicting? Yes, but it don't mean I shouldn't not be allowed to watch porn because a person don't know how to turn off their computer.
I like that you care about the awareness of porn addiction but we need to fix our social norms first and what we teach our kid about the opposite sex.
