Philosophy has many uses. Logic, for instance, may be worked out and expanded without the destructive forces of philosophy, as can many other boring branches of philosophy. But the great philosophical questions are destructive ones. If he hadn't been sanitized by philosophers, he would be, too. Though Plato actually wanted such a legacy less than did Nietzsche, he too would be seen as an explosion against the mundane uses to which he is typically put.
Philosophy can still be fun.
