>>>I cannot crop, manipulate, enhance, add or subtract from the image I get in the camera

Technically you or the film manufacturer have done all the above, you've cropped by your choice of focal length, the manipulation and enhancement has been pre-determined by the film manufacturer (I'm sure you have a favourite film or two!) who design their film to have a specific colour saturation and contrast curve. Thats basically all I do with a RAW file, the only difference is I choose the specifics instead of buying them pre-determined.
