This is a problem with many blockchain ideas. On one hand you get an immutable public record (and smart contracts), but on the other hand you need an incentive to use and mine the network...thus the in-built currency. But if that currency isn't seen as valuable...then the whole system falls apart. I'm not sure why Kodak didn't piggyback of an existing blockchain like Ethereum.
