“You have the option to change the kind of person you are, i.e. decide you’ll one-box in Newcomb’s problem at any given moment before you are confronted with it (such as right now), therefore you causally determine how much money you will receive once you play it in the future.”
If I am not the kind of person who would accept this reasoning, I can no more make myself into the kind of person who would accept this reasoning (even right now), than I can make myself into a person who has the dial set to the second position. Both are facts about the world: whether you have the dial set in a certain position, and whether you are the kind of person who could accept that reasoning.
And on the other hand, I can accept the reasoning, and I can choose not to smoke: I will equally be the kind of person who takes one box, and I will be a person who would have the dial in the second position.
