I don't see a reason why we would have a bear market if Satoshi comes back and starts moving his coins from any of the addresses you mentioned, and I don't see any reason for him to do that anyway, he can't risk his life by coming back and letting the world know that he is alive because he wouldn't be left alone if he does that. Who knows? He might be alive, watching everything, using Bitcoin not using these marked addresses.
I'm pretty sure that he would never reveal his identity or let the world know that he is alive even if he is because he knows it can become a life threat to him considering how many people, including governments, hate him.
