Unfortunately, what congress and the courts don't seem to understand is that the sale of copyrights is unconstitutional:

Article 1, Section 8, Clause 8:

To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries.

• "To promote the Progress of Science and useful Arts,"
• "by securing for limited Times"
• "to Authors and Inventors"
• "the exclusive Right to their respective Writings and Discoveries."

What about that is so hard to understand? The writers of the U.S. Constitution granted the right to "Authors and Inventors", not patent trolls or recording companies. Granted, "limited time" is debatable as far as how to best promote progress, but the right being granted exclusively to the content creator is pretty clear.
