@colomar that is actually my main concern with the 'free market' types... they generally only want free markets as long as it benefits them, but if they write a book, well sure they want copyrights! Of course they do! Otherwise they would have to work and be creative to make their moneys.
My main rule for myself is skepticism. Unilateral skepticism of any action that requires violent force or the threat thereof. Copyright is directly the threat of violent force.
