I still don't see the point. Are you arguing whether the author could ask for payments for copies? Sure he could. Even if there were no copyright laws. But only because of the copyright laws he can demand to be paid. Or you're arguing that "demand" doesn't necessary mean "ask for what is due, legally"? In this case I think what I meant was clear enough, since you seem to recognize that there's a nuance. If every word had only one strictly clear meaning, we wouldn't have numbered lists in dictionaries. (By the way, in my first sentence, by "point" I didn't mean a punctuation mark, nor did I mean an indefinitely small space.)
