Sounds like WoW is optimized for System 1 pleasures, and you explicitly reject this. I think that brings up an important point: How can we build a society/world where there are strong optimization forces to enable people to choose System 2 preferences? Once such a world iterated on itself for a couple generations, what might it look like?

I don’t think this would be a world with no WoW-like activities, because a world without any candy or simple pleasures strikes me as deeply lacking. My System 2 seems to place at least a little value on System 1 being happy. So I’d guess the world would just have many fewer of such activities, and be structured in such a way as to make it easy to avoid choices we’d regret the next day.

If this turns out to a physically impossible problem to overcome for some reason, then I could imagine a world with no System 1 pleasures, but such a world would be deeply lacking, even if that loss was more than made up for by gains in our System 2 values.

As a side note, it'd be an interesting question how much of the theoretical per capita maximum value falls into which categories. An easier question is how much of our currently actualized value is immediate gratifications. I'd expect that to be heavily biased toward System 1, since we suffer from Akrasia, but it might still be informative.
