I don't think the crown is keeping him alive in the way that you think! I think when he wrote, "this magic keeps me alive", he meant the crown was somehow protecting him in a way that the other humans were not protected. Maybe it allowed him to survive nuclear radiation or its magic was able to make him strong enough to fight off the beasts that threatened him. Why would a 47 year old man need to be "kept alive"? It had to do with nuclear fallout, so I believe if Simon were separated from the crown now, he would just go back to being human. I imagine the crown "froze" him in time. Whether you think he'll be 47 or revert back to the age he was when he first came in contact with the crown is up for debate.
