I think we are saying the same thing. I came across people talking about "dopamine addiction" a while back, and they were making the point that there's a sheaf of similar behaviors on different topics/substances. And that one had to learn to recognize the behaviors as a group. And I'll note that "take a break from everything" approach is both much older than this and can be very effective. People who do extended meditation retreats do basically what you describe. I once spent a week at the SF Zen Center's "Green Gulch Farm". No music, basic food, no tech. One could even sit at a table where nobody talked. I loved it. I have no idea if my dopamine levels changed. But it was great to set aside the frantic-feeling short-loop behaviors, accept a period of discomfort, and then feel freer once the compulsions/habits were past. As opposed to, say, quitting video games for a week but substituting more time on Twitter and watching videos. So I could see where they're going with it and I think they had good points. But it sounds like they have taken it too far.
