I don't think that rule expresses universal truth. These rules come and go. You have great writers who wrote famous books which don't follow these Storytelling that follows then becomes boring and predictable when they are widely used.

The junk adventure/vampire what not literature tend to follow all the structural rules and is as forgettable as it gets.

The argument with real life matter. Because when your storytelling rules make it impossible to tell real stories, then there is something wrong with them.
