He would not need to out himself.

A simple "Satoshi Nakamoto is not Craig Wright", signed with the private key of the coinbase of block zero or one would be plenty of evidence against Wright without ever revealing who produced the message.

But then, why would Satoshi, assuming he's still alive, ever lower himself to even get involved in this particular quagmire?

There's a reasonable possiblity that Satoshi Nakamoto is a Nicolas Bourbaki, aka a small collective of shared creators that also have a shared key - meaning that all, or a majority, if still alive to form a quorum, would have to agree to release early coins, sign messages, etc.

There's a reasonable chance this was a case of "try this idea and see how it works out" that only grew because of early "hoarding" which was a deliberate strategy at the time and there is no current consensus on releasing any more infomation or coins.
