I watched it, thought it was crap.
If nearly all guys use Internet porn, as he noted in his "lack of control group" remarks, then the natural question is this: Why do only some small fraction of them use it compulsively or perceive it as causing problems? We might also ask what percentage of the users actually experience erectile dysfunction concurrent with heavy porn use, and whether their ED (and perhaps their extensive porn use) might be caused by other health issues, such as being massively overweight from sitting at the computer and eating Cheetos for hours. But we don't get information about this stuff from the talk.
Also, lol at the way he portrays the supposedly wondrous new lives of guys who decide to quit porn. This is just the same "high" the body gives most people when they undergo any systematic deprivation of an accustomed physical pleasure. For example, new dieters, or people undergoing a fast, often talk about the same sort of feeling: remarkable "clear-headedness," a new sense of purpose and energy, and so on. That generally lasts somewhere from a week to a month, which funnily enough happens to be when people start falling off the "wagon" in droves. Oh well, enjoy it while it lasts, I guess?
"NoFap" exists in a context (Reddit) in which thousands of young males regularly lament their inability to find a girlfriend, get a date, or even talk to women their age like normal human beings. The pat anti-porn crusader "explanation" for this would be that porn has disfigured their perceptions of women and rendered their bodies deaf to arousal by real women rather than images. But what about considering the opposite causal chain: perhaps the ones who end up with a "porn problem" are just those ones who already had problematic, unsatisfying social and romantic lives. Porn might provide one more route to escapism for them, but it can't explain their need to escape in the first place. Just a thought!
