No it ain't.
Your porn addiction is fed via the Porn-Masturbate-Orgasm process.
So you cut out porn, but keep MO'ing, what do you achieve?
1) You want to sort out your PIED - well now you're just going to have fap-induced ED instead, and you'll be spending most of the time with your balls drained and zero confidence. Good luck getting it up for a real woman.
2) You want to get the time back in your life to do something useful with it - well you ain't, cause you'll still be edging for hours, fucking up your life further.
3) You want to stop the ever increasing degenerate behaviour? Well, what are you going to fap to? Memories of porn? Softcore? That girl you saw on the train today? Then you want more, so you eventually revert to fantasies about being fucked by your neighbour's dog. Before you know it, you're back in your bathtub with a 20-inch dildo up your butt, licking your own shit off your fingers while fapping yourself until you pass out.
Also, what defines "porn", apart from the obvious degenerate hardcore shit on PH, etc?
Is softcore porn?
Erotic hypnosis (no visual stimulant)?
Sex scene in a film?
Erotic comics?
Amateur-drawn My Little Pony erotica?
If kicking porn addiction is just about not watching porn, then I can dress up in my fluttershy fursuit, stick a horse tail butt plug up my arse and fap myself for hours while watching the first season of MLP (that's not porn, right?) before finally jizzing all over the VHS player. And that won't make me a porn-addicted degenerate?
Something doesn't add up, anonybro.
