Alternate phrasing, “Oh, you could steal the townhouse at a 1/8billion probability? How about we make a deal instead. If the rng rolls a number lower than 1/7billion, I give you the townhouse, otherwise, you deactivate and give us back the world.” The convex agent finds that to be a much better deal, accepts, then deactivates.
I guess perhaps it was the holdout who was being unreasonable, in the previous telling.
Or the sides can’t make that deal because one side or both wouldn’t hold up their end of the bargain. Or they would, but they can’t prove it. Once the coin lands, the losing side has no reason to follow it other than TDT. And TDT only works if the other side can reliably predict their actions.
