People still pay for movies, music, and SW today, so our current balance still creates economic rewards for production, despite piracy. Would you call our society today a "SOPA-style surveillance system" ?
Not at all, although I would argue that our current system today is in serious transition. Sharing is getting easier and more distributed, that's what's prompting the SOPA style solutions. Staying where we are now isn't an option thanks to the HN crowd continuously working on new ways to connect and share bits with their social circles.
