I think the deliberate enjoyment of those things is absolutely something to value, and maybe coloration only has a small role in incentivized passive scrolling through media, but I think it's a hell of a lot better to not shit where you eat. If you want to play games, use your game playing thing, don't put yourself in a position where game playing or YouTube is easily capable of competing with other material that's also valuable but not nearly as stimulating or chance oriented.

I think it's pretty common for people to spend hours a day on their phone doing absolutely nothing of true substance, because activities of substance require intention.
