I agree with both of you, but on the other hand, wouldn't it be more harmful to leave this "identity discovery" to malicious people alone? Satoshi's posts are open for public scrutiny. It is already apparent by now that there is a host variety of theories and evidence, such that nobody can be certain about a particular individual. I don't think that would be possible if simply curious people weren't involved in this.

I like thinking it as cryptographic security, wherein well-intentioned people attempt to break it, to ensure it is unbreakable.
