Oh yeah ironically I think the lectures are even more important to do the story justice in a filmed medium. The comic keeps demanding you turn your brain on but people resist that in movies and movies (and tv) struggle to get people interacting critically with themes. The movie's cultural impact was politically confused when you could do a voice over of him explaining anarchism during one of the scenes, a montage, or broken up throughout the "The Land of Do-As-You-Please" section of the story or in Evie's lessons.

I don't think it would've been super popular among audiences or the production company, but it would've been really hammering in the themes and points that the comic was appropriately heavy handed with.
