My printer prints out documents. Those documents are not printers.
My cat produces hair-balls on the carpet. Those hairballs are not cats.
A human creating an artifact does not make that artifact a human.
But that's not the argument GP made. They said that there's nothing at all that's human about art or such things, which is a bit like saying that a cat's hairballs don't have something vaguely cat-like about them, merely because a hairball isn't an actual cat.
