another point is that a planet-buster level doesn't need to be able to destroy planets, if they can defeat someone who can do that then they are at that level too.

For example, a man killing a giant who can destroy a fort, the man can't destroy a fort but that doesn't make him weaker, it's just a difference in accomplishable feats depending on body dimensions.
