Satoshi's fortune (1.5Mbtc) is almost as large as the daily volume (1.9Mbtc) of the entire market... its sudden change from dormant and, for all purposes inert, to "potentially market-destroying" would be way too spooky.

Even a single satoshi leaving one of his known wallets could spook enough people to cause a crash. I can't speak for other investors, but even though I have been long in bitcoin for years, I would be out in a heartbeat, for at least a month.
