This is just another reason the idea of "lost coins" is el stupido. The ONLY person with the rights to move bitcoin is the holder of that (those) private key(s).
Period.
And it is their right to move them as they please. Even if it frightens people, or means they are rich, or crashes the price. Or proves they are Satoshi, or ANYTHING. PERIOD.
I am not scared. I still have the keys to my coins.
