Are you making creations available right now? In that case, why? Surely you are aware that currently, others can use your work under fair use and that your copyright has an expiration date? I don't think anyone is (seriously) suggesting doing away with copyrights entirely. The real question is: how much incentive do you really need? Would you really say "well, if I put work into this, after 50 years anyone can make money off of my effort, so f..k it!"? I have a feeling 20 or even 10 years would be sufficient payback time. After all, patents are limited to fairly short times and it's not like there's a shortage of patent applications.
