To sum it all up: Copyright shouldn't exist. It doesn't protect the original creator, it only stifles the continuing creativity and natural flow of progress.
Well I wouldn't take it that far. As a songwriter and film maker I have a right to request payment for copies of my works. I just call for common sense. If you let something slide for years and then suddenly get a bug in your butt about it, well, you're full of ****.
Rumour has it Earthbound is in limbo because of some music allusions to Beatles' songs. Well sorry, Paul and Ringo, but the game was on the shelf back in 1995 and was probably in stores for a few year and you could have made a stink then and there but you never did.
The idea of copyright is supposed to be such that people don't outright plagarize you or sell bootleg copies of your work at the flea market. It should only be to prevent people from profiting off of your work without permission or from outright stealing it.
