The right of copying... Copyright

In the visit we had from Diane Graves, the University Librarian, on Tuesday, I learned different aspects about what copyright entails. From the subjects she mentioned, the fact that impressed me the most was the time spam copyright has on works. I had no idea that I wouldn’t be able to officially copy Nemo for another 89 years!!
Even so, another matter that really was contradictory in my mind was the copyright case of “Orphan works”. If there isn’t a rightful owner to claim their work, then why even bother? Any way the copyright industry might be more directed for big companies trying to protect their fixed income than on articles. But probably there is more to a copyright license than the protection of someone’s salary. Why are “Orphan works” copyrighted when there is no possibility that the author might be prejudiced by copying the work? Well, the answer to this question is to meet their objectives. One of the purposes of copyright is to promote innovation and creativity. This way other artists will find the way around their problem on their own instead of depending on someone else’s work. This is my final side on the subject because this way there will be more possibilities and “Orphan Works” can still be used abiding by the “Fair Use” Policy.
