Then there is nothing stopping you from doing just that...Just because the protections exist does not mean you must avail yourselves to them, you can give your work away for free all you want or let others take your work reproduce it and sell it as their own (maybe even take credit as the original creator).
However, if your saying you need to create your work off anthers work which is copyrighted and they want to enforce the same, then I would say IP is not what is stifling creativity, rather an unoriginal artist with no creativity to begin with.
