I this this a dangerously weak argument against things like SOPA. Congress deals routinely with technical matters far outside the experience of most of its members. Very few members of Congress can pilot a plane, price an option, inspect a copper mine, gauge the damage of X parts per million of some contaminant in the water supply, or, for that matter, provide for and maintain a Navy like the Constitution demands of them.
The argument against SOPA can't be "Congress has no business wading outside its technical competency"; it has to be, "this is a bad proposal, intrinsically, for reasons X, Y, and Z".
That can't be used as an argument against SOPA, but having technically competent congressmen would certainly help to prevent this kind of thing in the future.
