I think it was you who derailed this particular subthread by confusing the concepts of "moral rights" (being named as the author of something you have written) and "morality" (not being stolen from, or randomly killed).

This confusion was no doubt intended by those who coined the term "moral rights". But they are not the same thing. Copyright law is not needed to enforce moral rights, as you can very well see from the fact that we do acknowledge the creators of works that predate copyright by hundreds or thousands of years. We can freely copy Homer's works. And we do. Be we don't remove his name from them.
