The argument your trying to push should stick to recasting, not licensing. Fact is licensing is one of the more flexible points of collecting. Ask some of those talented sculptors your defending how many unlicenses likeness' they've sculpted for comission and sold to people, even multiple people because people want something they will buy it, license or not.
Now recasting, taking someones original work and re selling copies is wrong yes, but as long as people are willing to buy it they will keep selling them. Because in a community where the items are of limited production quantitiy, demand will always outstrip supply and whomever can come up with the extra supply will do so, and make money doing it. At the very least i can say for this statue at least they tried to do something different with it, its more akin to a custom than a direct recast, they at least reposed it. Its much like custom action figures using existing parts and sculpts people use slightly modified to make something else and sell it on ebay.
Personally im of the mind similiar to fox, its choice, if you wanna buy it, buy it, if you dont dont, but dont expect everyone to see things the way you do, or feel bad for buying something you think is wrong, if its something they want and its not technically illegal to do so.
I dont think theres a point in berating people who buy recasts, because simple fact is they chose to do it, wether they knew what it was, they knew that they wanted it, and they chose to buy it as its their choice, not yours, its fine to complain about the people doing the recasting, but theres no point in trying to rip on the people who buy them, even if they are supporting the people doing the wrong, its not going to stop the people doing the wrong complaining to the people who bought it.
