Quote - It would give the vendors here a better income of some of these pirate sites could be forced down.

I don't know about that. Vendor's revenue is probably tied to disposable income of consumers more than anything else.  For me I used to buy at least 5 models every month but now I don't have the disposable income anymore, so now I purchase a model every 6 months or so. 

The assumptions that are made are

#1:  That they can actually find enough pirate sites including their sister sites

#2:  That peer-to-peer software falls under the same category as "website."

#3:  That they will even have access to a pirate site.  Even today there are pirate sites that require membership and passwords in order to access stuff.  Fileshare sites have the ability to have passwords as well. 

#4:  That all pirate sites will be in english? A person could make a in another language and it wouldn't even show up in the U.S. search engine.

#5:  That non-IT, non-Technology congressmen and congress women have the necessary knowledge to even address such an issue.  I wonder how many IT professionals did they consult with?

They came up with this idea based on the assumption that they actually know and understand the how the Internet works.  They probably don't know anything beyond the search engine.
