I don't think you can infer consumer positions on IP law from positions on who ought to get paid or how much they should be paid. Many of those same consumers, and indeed many of the artists, feel that fan art of your favorite characters should be legal and unrestricted so long as nobody's making too much money off of it.
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.
