Getting rid of copyright is going to make that problem worse not better... I'm wondering if you are reasoning correctly about this.
I'd say that random people, if they reuse a copyrighted material, are a lot more likely to veer far off the beaten path than the big studios. Fan fiction, even if building on previous materials, seems to be much less repetitive to me.
Your point was studios recycle IP a lot.
My point is without copyright studios would recycle it even more.
And your point now is that it would be higher quality.
