yeah, of course. would be really easy to just go off & do your own thing / get away from everyone else.
Essentially if there was a godly creator they would be a Flat Earther if they were smarter. In the real world though Fat Earthers are wrong, and the globe disproves intelligent design.
Might also be limits? Consider making our world like designing a video game. Could literally anything be designed or would there be some universal limits?
Those benefits work in a universe that is hands off. A creator should have been able to come up with a better system than one that lead to most species becoming extinct.
I agree there are optimizations to be made, but every optimization could break something else. (eg allow FTL, now have to deal with time travel or something)
