You touch on another flaw in the original article's reasoning: By eliminating copyright protection of all kind, you make it harder for people to reward the original artist.
Right now, people who want to get a copy of a work for free know what they're doing. They're going to Pirate Bay or some other website instead of Amazon, while people who are happy with paying artists can do so relatively easy (how much publishers are taking is another issue). If you were to eliminate attribution requirements, I'd be free to republish your works on Amazon uncredited or even (depending on the laws that do remain) claim them as my own. Now people have to do additional research to determine just who the actual artist is and whether they're rewarding the right person. Your legal recourse may be limited.
