No, the problem with being dumb is that, while you get to avoid some of the existential mores, there are other pains that you suffer as a result. You'll make (comparatively more) mistakes that are obvious in hindsight. You'll leave a beer on the ledge while you make a funny emote and your flailing arm will hit it into the pool below. In addition, your interpersonal relationships feel more random in terms of success and failure. Another attribute of intelligence is using of theory of mind to help know when an action makes those around you happy and sad. It's the difference between thinking that North Korea and Iran are just violent maniacs and thinking they might have legitimate grievances with the US and its vassals. If you "only made out with her because our rule is that you can't fuck other people" then you'll likely lose your relationship and think they were being unreasonable. Your relationship with your boss will be generally amiable but sometimes they just explode about random things about your work. These random acts of punishment will extend to the self and nature as well. All sorts of tummy aches, head aches, and bad moods are sidestepped entirely via introspection and adaptation. So many valuable things in life go more smoothly the more you're able to use that noggin to think about responses to actions and adapt because of it.

Or whatever haha
