Perhaps if there was a good chance I could prolong my "still healthy" years by 20 years or more, I should take it. But it seems like disappearing for 10 years would break a lot of things. People will die, friends will move on... sounds like a rather bad deal still.
Buy every politician and the media to become the effective ruler of your country, then use your influence to improve the lives of your compatriots, overhaul the entire political system and media to add safeguards to prevent anyone from ever again doing what you did, create a just society and become a beacon of hope to the world.
I'm not sure if I would take it either. I would feel better earning (a fraction of) the money instead of just sitting around for it.
