Whether or not they're as good as manufactured weapons in real life is beside the point. The designers make the conscious decision to put a worthless claw attack in the racial block or replace it with a teleport, hellish rebuke, flying, or any number of other racial features that PC races get. They could have put something generally useful in that space, but they chose to put something that is mostly useless. I have no idea if the satyr is loaded up with great features, but there are certainly PC races where natural weapons seem to be included as if they were useful.
