Alternatives to the Hero's journey

We are so used to having some conflict in every narrative that it may look like there are no other compelling options. In theory, there is nothing wrong with having a story without rivalry or struggle, where everyone lives happily ever after right from the beginning. There could be a story about a hero who only fights weaker adversaries, defeating them without difficulties (cue recent Disney movies). However, for some reason, we find them irrelevant. We take for granted the presence of common themes in our culture and have almost stopped valuing them. The abundance of conflict in narratives reflects our nature and some argue even implies a rejection of the utopian idea of having a life without struggle. Whether these myths represent distilled knowledge or a glitch in the matrix, having them everywhere proves their importance.
