>What if we were civilized enough you didn't have to worry about anyone building their own atom bomb?

Then we'd be something other than human. You'd need a species that values all members equally and has no preference for those in the same social group (or family, etc.). Likely it also means members cannot value themselves above other members. Without all that "civilized" simply means that some group gets oppressed and isn't allowed to fight back in any way.
