The argument has been made by quite a few people that satoshi's alleged stash is a cloud over the market since he could decide to start selling it at any unknown time.
Satoshi could also decide to reinvest his stash back into Bitcoin R&D, education, marketing, bootstrapping, etc.
Imagine the headlines if He started to pay people (in highly-collectible OG Bitcoins) to teach farmers/tutors/doctors/unbanked/emigrants how to use Bitcoin!
I really don't think it will make the "headlines" you're thinking about, when it comes to mainstream news picking up on it... but in the bitcoin community it would be huge news. But why would he pay people to "teach" them how to use his coin? That doesn't really make any sense.
