OK, I get this. Really, I do. I've spent many many hours doing "nothing" just like this, and those have generally been happy times. But ... how would that change if you had a lot more free time? Could you spend all day every day in such a state? Would it be healthy if you did?
The reason I ask is that I've had to grapple with that question since I retired. Probably will even more so when my daughter leaves for college. And as much as I enjoy doing "nothing" I find that I just can't do it all day. I have to be doing something, which brings us right back to the issue of low-effort low-reward activities (e.g. doomscrolling on the internet) vs. high-effort high-reward activities (e.g. hobbies, community involvement, travel). I force myself to do the latter first so I don't lose the ability to do hard(er) things, and there's still plenty of time left over for the low-effort stuff.
I suggest that your "war" only needs to be fought because you don't have enough total free time, and it will seem like a very different war when that changes.
