> There's zero benefit to society

Wouldn't it result in additional tax revenue while preventing Disney's movies from proliferating throughout society unimpeded?

In all honesty, I really think you should think this idea through. Compared to the status quo, where we get zero tax revenue from intellectual property, this system would guarantee an expiration based on commercial viability. It couldn't sustain forever because the scale would always accelerate at a rate faster than any economy could sustain it. But it would have this additional benefit in that the more some intellectual property becomes commercially sustainable, the more revenue society can collect.

How does that even begin to approach horrible when it's magnitudes more equitable than the status quo?
