No, we shouldn't.  There is absolutely no good that could possibly come from identifying satoshi at this point.  It could only be bad.  Attacks on his personal character to discredit Bitcoin.  Maybe using his personal political beliefs to try and splinter the community.  He could be arrested for his creation.  It would make him the biggest kidnapping target on the planet...  Why would he want to be known at this point and if you can agree he wouldn't want to be known, then why would we go out of our why to try and identify him?  Seems like a shitty way to give thanks to the person who gave life to the concept that will change the world.
