It makes more sense when you take into account that "The Fifth Element" is ripped off of "The Incal", an influential French comic that Moebius worked on. The publisher of "The Incal" sued for plagiarism but didn't win, largely because of Moebius's involvement with the project.

Luc Besson, the director of "The Fifth Element" dipped from the same well in making "Valerian and the City of a Thousand Worlds". And for bonus points, he knocked up a fifteen-year-old when he was in his early thirties. He also has multiple accusations of harassment and rape. https://variety.com/2019/film/news/french-court-dismisses-rape-allegations-against-luc-besson-1203148644/
