Copyright could be changed to provide its same benefits (incentive to create) while removing its harmful and very real costs to society present in its current form:
-Shorter term-most creative work has, within 5 years, either made a profit or never will. Copyright should not be longer then this, then-it still would provide financial incentive without providing an excessively long restriction term.
-Returning to mandatory registration would eliminate the problems of "orphan works" and "untraceable holders"-anyone who wishes to present a work commercially would make use of a free and easy registration system, while allowing use to be made of the work of those who do not choose to explicitly register.
-Copyright should be considered an industrial regulation preventing unlicensed commercial use, not a restriction on individual consumers.
