AHHH, but what if the film was $100 a sheet or roll? I'm pretty sure that the demand for film and then its supply would dry up pretty damn quickly.....

100$ per roll will not happen.
One can make a roll of 35mm film (perhaps in plastic casettes in the future) for les than 10 USD (todays value) in very small quantities in 100 ASA or less. Making 400 ASA is a bit more difficult. More than 400 ASA I would leave to digital.

Our small factory can make quantities of a few thousand rolls of film at about 3-5 USD per roll.
