Monomyth Structure

For the most part, each story is told in a fairly similar fashion. They follow the general mold of the monomyth chart, but not to an exact science. Some stories are not completely in order, and some are missing certain sections of the monomyth. But, despite this, I think the main idea of the monomyth structure is still valid. People have figured out how to get the viewer's attention, and this structure has been followed over and over. Whether it's accidentally followed or followed on purpose, it's still followed mostly perfect. In your opinion, does the story have to contain each of the sections of the monomyth chart as well as be in order, to be considered using the monomyth structure?
