Build it, film and paper will be around for a while. There are currently too many suppliers in relation to the demand but once it settles down, things will be more stable. Even in the worst case senario, no commercial providers at all, you can still work. Make paper negatives, use alt processes, coat glass plates, etc. I have always enjoyed photography and I refuse to let anyone stop me from continuing to enjoy it. I can, and will, make all of my own supplies if needed, and I suggest that anyone else can do the same. There are so many historic processes that can be done at home that if needed, you could be totaly self sufficient.
