But one thing's for certain though, whoever started all this definitely has enough btcs to last him and a couple of generations a comfortable life.
If that was Satoshi's main goal, some of the coins would have been sold or spent already, and that's not the case. On top of that, try to spend these coins, it's next to impossible to do anonymously because of how different agencies around the world would love to have a word with him, and extort him till he coughs up that whatever governments think he "owes" them.
Even worse, one tiny satoshi moving out of one of his thousands of wallets will result in a massive crash. I'm certain that bots are constantly monitoring these addresses to spot activity and dump as soon as they can.
