Black keys are a limited resource, so it isn't an option for everybody, especially for players who'd want to save them for PR materials. There are also other ways to get Harpies/Sphinx's, so comparing the two using black keys as the only metric isn't really a fair comparison. That being said, both options are still valid depending on your inventory and where you are in the game, so calling one option a waste simply isn't good advice for everyone.
