I can't imagine this scenario, satoshi nakamoto was behind the development of bitcoin and which is anonymous to this day, why would he think to destroy it?
if he does, he should find a way to withdrawn some money to his daily needs but  I'm not sure he could do it without leaving a trace and you know that this world if full of curiuse poeple who will not hesitate to visit him at home to see if he is really human or just a creature came from another planet.
