Damn this reply function!
@ChipBennett, I apologize. I was incorrect about charging. From Section 4 of GPLv3 "You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee."
So, yes, I agree it would be legally very difficult to restrict someone from reselling a GPL-licensed work. I suspect there is a way, but until this is all tested in a court, we will not really know for sure.

In fact, I was hoping the whole thing would go to court back when Chris Pearson challenged the idea that plugins and themes are derivative works under the GPL. Until that's tested in a court of law, it's all very much debatable, no matter what anyone's feelings are on the subject.

Also, as a side note, thanks for the debate and discussion. When I'm off of the next couple days before the Christmas holiday, I'm going to make a point of reading the GPL very closely. There may be some other things I've missed that would be good to know! Celebrate the miracle; internet debate opened a mind! Thank you!
