will this technique work?

I don't think you can get addicted to no PMO. I think the reason why is because our brain does not work entirely psychological but also very physical. I guess the parts that throw the Dopamine out of the brain only gets stimulated be specific things, like sex, PMO, or Drugs and stuff like that. It is a physical addiction, not a psychical addiction.
I am no scientist. I know nothing. This is just something that sounds Logical to me, without any proof!
So I think you can actually like not to PMO, but only psychological. You won't really get those Dopamine Bursts and stuff like that

 

Yours is an interesting concept. Sort of like "Get high on life and living!" - why not? I don't think that I would classify Nofap as addiction, though -- unless one becomes so overly obsessed with stopping PMO that it eats away at all their life and time. Or, one could, perhaps, become addicted to the Nofap website, even, if it becomes a surrogate friend as a social website, replacing real friends and relationships in life, that sort of thing. Even health fanatics can go too far at times, when it consumes every aspect of their life to the detriment of other areas - such as relationships or growing in other areas in life than just physical health. But the simple freedom of Nofap addiction would not itself be another addiction. An addiction is something one cannot easily cease doing, even if one wants to, whereas if you are living a Nofap healthy lifestyle, it would probably be very easy for you to get addicted to fapping if you started up again. Yet, with your great consideration of reward centers, indeed, we can use positive reinforcement to strengthen virtues that we are trying to achieve (like Nofap) - watching one's counter progress upward can be a positive reinforcement if it gives one satisfaction to see it increase each day. Also, you can give yourself a reward now and then when you have reached a goal. This strengthens the desired behavior. Such rewards that strengthen Nofap perhaps induce a dopamine hit as well, but in a positive way and probably in a small amount, but the dopamine flooding of the brain that is brought about by constant PMO is probably greater and unmanageable in quantity; hence, the problem of the very addiction. Dopamine itself isn't the problem - we need this chemical in our brian to stay alive even (as a person and as a species). Eating good food triggers dopamine, for instance, in a moderate fashion. It is the immoderate flooding of dopamine via addiction that become serious and destructive to one's quality of life.
