The reason is that no matter what class you choose, you get to pick one starting gift. The master key is one of those starting gifts. So basically if you choose the thief class you get the master key and you can pick another gift, whereas other classes have to give up their starting gift if they want the master key. But that doesn't really matter, since the other starting gifts are very mediocre, so you might as well pick any other class + master key gift if you really want the key.
