Film photography is my hobby and I think that there isnāt anything that would prevent from exposing a displayed image on a piece of film, except for the cost.
Depending on film it might not be easy to tell exposing an image from a real picture.
The āhybridā digital instax cameras work this way, itās just a digital camera that has a way to internally expose the picture on the instant film.
Itās trivial to do analog prints from digital images too, just requires an inkjet printer and a special film to print out the ādigital negativeā.
The only way in which it may succeed as a deterrent is that it actually costs some money (film and processing is not cheap) and requires actual work to do those extra steps.
Well, the other thing is that except for the instant film, thereās no instant gratification in this hobby. Even when one processes at home, the typical time form a photo to a print is measured in hours.
