The reason people like film is not just the way it looks (which you've been able to fake ever since the "Hipstamatic" app came out decades ago) but precisely because it costs a lot to shoot and you don't know what you have until you develop the film. It puts much more a premium on competence and selectivity in shooting. It's the same reason that a photorealistic painting is much more impressive than a photograph.
That could be simulated too: remove or disable the preview screen and install a tiny, slow, but really expensive gold-plated SD card.
