OP, I don't think the world cares anymore about discovering Satoshi. Bitcoin is on autopilot, so to say. Whether Satoshi appears from the blues or not (that's if he's an individual and is still alive) doesn't matter any more. Bitcoin is able to attain it's height because of its security features which have earned it trust from the community. If anything, the world knows of Martti Malmi (Sirius) who's an important person in the development of Bitcoin but that hasn't in anyway affected Bitcoin. Malmi grants interviews and talks about Bitcoin and an insider but people don't seem to care what actions he gets involved in. They don't see him any differently apart from his ingenuity. Maybe that's how the world will react to Satoshi if he surprisedly appears on the scene now. What if in the likely case that Malmi turns out to be Satoshi, I still believe life will just go on as usual. Except for him who will be needing extra security around himself.
THE reason of high trust of bitcoin is that there is no hidden code, no back door. no red button that can cause an instant sell off of all coin by any reference client dev
That should be it and not because Satoshi's identity is hidden.
