because film is physical, its its "side effects" are naturally occurring as a result of the processes... fortunately, natural occurring phenomena are naturally occurring and are superior in their "pleasing to human perceptibility" than electronic equivalents... Film grain is so small, it has been for so long, what you see if you see it is generally a result of either artificial grain (because they de-noise thigns so much they need grain to make it look like a real film... arg) or because they are using many generations down copies of copies of tapes because they are either lazy, they threw out the original tapes, or they can't or wont get to them. Grain, if it is natural, is good. Removing grain is not possible without ruining the film, its like when you try to remove noise from audio.. it doesn't work because the filter cant always determine what is noise and what is true signal.
