Okay, yeah, I know how the law works. I guess we kind of got distracted from my original point, which is that ownership in this sense isn't ownership as most people know it (like saying this is MY computer). An artist "owns" a song in the same sense that the inventor "owns" post-it notes.
But there's no law preventing me from copying post-it notes using my own resources, so long as I don't call them post-its and try to sell them - just keep for personal use. I don't see why different things need to apply to digital media.
