The real problem is that it's hard to predict the commercial success of a creative work, especially when it doesn't exist yet. Publishing is a hit-based where most books barely sell, but then a few make more than enough to cover the losses incurred by giving long-shot authors a chance.
With much shorter copyright terms, I guess only sequels of already-popular works would get significant funding.
This is madness.

Even then - who would buy it if they could just wait two years and read it for much less?
