If that were strictly true, then SOPA would have passed.
As for SOPA - say hello to SOPA 2.0 http://www.uspto.gov/news/publications/copyrightgreenpaper.p...
In essence however, SOPA in some form will pass and this document represents a new approach.
As someone posted before - it does not matter if it is SOPA 14.0 or SOPA 22.0 - it just needs to pass once. Very few examples of legislative repeal exist outside of social equality.
Future dystopian writers can certainly draw upon it as a non-fiction source.
