Well if anyone can duplicate it, then is it really worth anything? It's like urine...anyone can make it. Should we all pay royalties to the first guy to ever take a leak? Maybe the incentive to make something new should be the enjoyment you get out of making it. If you can make money off of it, great. The copyright should only keep someone else from making money from it. It shouldn't stop people from copying your idea and making their own for their own use. That is anti-productive, and it goes against the very thing this country was founded on - freedom.
