Piracy is just copying information. The only "harm" it might do is make the person selling the information lose a sale that might never have taken place (I, for one, would not have bought the things I have pirated if I couldn't have pirated them). Basically, I don't think that I should be less free just because someone wants to make more money.

If I was in charge, laws would only restrict the freedom of the people for the safety of others (and even then it would only do so by making harmful acts illegal, not by spying on them or other crazy things). Intellectual property would only outlaw copying for commercial use, which would allow artists to make money from movie theaters, concerts, etc.

I'm sure many problems would arise from such a world, but I doubt that they'll be worse than the problems from the current system, and I'm sure that given time and actually implementing it, the kinks could be worked out.
