First:

I truly believe that they don't matter as an individual when looking at their creation as a whole. It matters among their loved ones, and for that person itself. Why do you need more... importance? From who? Why do you need to matter in scope of creation? Is it a creation for you? Then why publish it? Is it a creation for others? Then why does your identity matter? It just seems like egotism with extra steps. Using copyright to combat this seems like a red herring argument made by people who have portfolio's against people who don't..

You are not only your own person, you carry human culture remnants distilled out of 12000 years of humanity! You plagiarised almost the whole of humanity while creating your 'unique' addition to culture. But, because your remixed work is newer and not directly traceable to its direct origins, we're gonna pretend that you wrote it as a hermit living without humanity on a rock and establish the rules from there on out. If it was fair for all the players in this game, it would already be impossible to not plagiarise.
