Could that domain not just be really small, such that the ratio of outcomes you'd accept the bet at get closer and closer to 1? It seems like the premise that the discounting rate stays constant over a large interval (so we get the extreme effects from exponential discounting) is doing the work in your argument, but I don't see how it's substantiated.
