You're missing the fact that you can actually develop the film at home in your own darkroom, and have total control over the type of film, the chemicals used to develop it, the temperature of the chemical baths, under and over exposure, push processing and cross processing. Sure, most of these decisions have to be made in advance and apply to a while roll at a time, but 120 film on a 6x7 camera is only about 10 shots. Better yet, using a frame camera you shot individual shots on massive pieces of film and can develop it exactly the way you want.
Once you have the negative developed, it's child's play to scan it into a PC and do anything that could be done to a digital photo. Alternatively, spend a few hours in the darkroom developing prints the old fashioned way. You have quite a lot of control at the print making stage, from dodging and burning, contrast filters, toners (sepia, chocolate, etc)
