The difference between film and paint is that with a little skill it is possible to make your own paints. Film? Not so easy.
Film sales have been in decline for over 10 years. Before that, prices were subsidised by huge numbers of people who developed one film a year: christmas trees at each end of the roll, beach balls in the middle. There may be a vinyl-like resurgence driven by the nostalgic but I tend to doubt it. At some point film will simply be too expensive to produce. If you want to shoot film I would suggest you buy what you can and keep it in the fridge against the day when it is no longer available.
