As a lesser thought: currently, when you publish a book in the US, you are legally required to send a copy to the Library of Congress. I could see the same thing working for software, requiring a submission of source code to some central publicly-accessible digital library. No licencing requirements beyond "people can read this," but that'd still be an unearthly boon to, say, security researchers.

Argument by swearing is kind of weak. There is plenty of evidence we've gone too far towards producers in terms of intellectual property, but eliminating everything: copyright, trademarks and all patents seems like it might require a bit more than a few F bombs to back up your point.
