If I were forced to pay $100 upon losing, I'd have a net gain of $4950 each time I play the game, on average. Transitioning from this into the game as it currently stands, I've merely been given an additional option. As a rationalist, I should not regret being one. Even knowing I won't get the $10,000, as the coin came up heads, I'm basically paying $100 for the other quantum me to receive $10,000. As the other quantum me, who saw the coin come up tails, my desire to have had the first quantum me pay $100 outweighs the other quantum me's desire to not lose $100. I'm not going to defect against myself for want of $100, and if you (general you, not eliezer specifically) would you should probably carry a weapon and a means of defending yourself against it because you can't trust yourself.
