You're right. It's wrong to think that all of those people are busy writing to congress demanding new laws be enacted. The problem is, the vast majority of people (while possessing a vague sense of right and wrong) do not understand how IP law works, and what the tradeoffs vis-a-vis the public good are. I'm sure many among the supposed consumers in this survey think something akin to "there ought to be a law" -- a sentiment somtimes echoed by readers of this very forum.
