Though I can appreciate where you're coming from, support from the casual consumer equals long-term viability. You need that buy-in if this is going to succeed. I worry that $3/shot film doesn't stand a chance if you don't also have the revenue that comes from the 250 crummy shots at a house party.
Maybe there's a compromise point. Perhaps market a far cheaper ($.50/print) but slightly lower quality film alongside a professional, $3/print, higher quality film. That's the difference between this being adopted by the mass market and surviving long-term, versus being a short-lived boutique medium for wealthy artists only.
I'd argue that part of the appeal of instant film is that it's not a mass market product any more. There's no way it could compete with the billion smartphone cameras every single person at that house party already has in their pocket 24/7.
The appeal is novelty, nostalgia, simplicity, tactility, etc. It's in the same category as vinyl records.
