To be fair, if we are incorporating TLG into canon, then most likely the only reason why Mufasa took charge of patrolling/protecting the borders in TLK was that there was no Lion Guard at the time. Had Scar not killed them all, who's to say Mufasa would have been doing that work himself? He might have delegated such duties just as Simba does now.

Though it still doesn't excuse Simba and Rafiki pushing the responsibility of the safety of the entire kingdom onto a group of cubs. Kiara has to wait until her parents grow old and die before she is granted the responsibilities of being Queen, but her baby brother and his friends can run off at all hours to battle dangerous predators? A+ parenting there, Simba /sarc
