If it wasn’t for THX-1138 you cynicism might be warranted. The other factor is that the simple matinees are just as tied to the hero’s journey as Star Wars. The hero’s journey is tied to stories from the beginning of storytelling. Lucas experienced his own hero’s journey in producing the movie.

Finally from what I know Cambell ended up living on Skywalker Ranch. I see no reason to minimize connection.
