I support environments that enable and encourage the production of new creative works. I believe that copyright in some form is necessary to support such a system.
"A distinguishing characteristic of intellectual property is its "public good" aspect. While the cost of creating a work subject to copyright protection—for example, a book, movie, song, ballet, lithograph, map, business directory, or computer software program—is often high, the cost of reproducing the work, whether by the creator or by those to whom he has made it available, is often low. And once copies are available to others, it is often inexpensive for these users to make additional copies. If the copies made by the creator of the work are priced at or close to marginal cost, others may be discouraged from making copies, but the creator’s total revenues may not be sufficient to cover the cost of creating the work. Copyright protection—the right of the copyright’s owner to prevent others from making copies—trades off the costs of limiting access to a work against the benefits of providing incentives to create the work in the first place. Striking the correct balance between access and incentives is the central problem in copyright law. For copyright law to promote economic efficiency, its principal legal doctrines must, at least approximately, maximize the benefits from creating additional works minus both the losses from limiting access and the costs of administering copyright protection." - Posner, 1989, An Economic Analysis of Copyright Law
