If a savant has perfect recall, remembers text perfectly and rearranges that text to create a marginally new text, he'd be sued for breach of copyright.
Only large corporations get away with it.
If you draw a Venn Diagram of plagiarism and copyright violations, there's a big intersection. For example: if I take your paper, scratch off your name, make some minor tweaks, and submit it; I'm guilty of both plagiarism and copyright violation.

Did you not literally comment the following?
>A new research paper is obviously materially different from "rearranging that text to create a marginally new text".
What did you mean by that, if that's not your claim?
