Morally and economically I could not disagree more strongly with this point of view. The act of creation does not mean an entitlement to tell other people who you have sold your creation to what they can do with your work. And the U.S. Constitution is pretty clear that the purpose of "exclusive rights" is to promote progress in science and useful arts - not to track down people who have exhibited no interest in being compensated. Tracking down owners of rights to orphan rights simply poses an additional cost to creating new works based on old works and enjoying old works - the additional incentive provided to authors is less than my clapping them on the back and saying "good job." The Constitution certainly does not say that nobody except the author can profit from an author's creation - and people can, should, and do profit greatly from works in the public domain.
