As much as I despise SOPA, and realize this is little more than an wealth transfer to the entertainment industry from the internet industry, I will acknowledge that DNS blocking is actually a pretty efficient way to stop your average person from accessing web sites.
Remember - SOPA is not designed to stop piracy - there are hundreds (thousands) of mechanisms for file sharing that your average government policy will have no impact on. What it will do, is make it burdensome for 99% of the non-nerd population.
As long as the 99% are impacted, the entertainment industry really don't care about that final 1% trading files to their hearts galore. This isn't about principal - it's pure economics.
