Either I don't get it, or you are misapplying a cached thought. Please explain to me where my reasoning is wrong (or perhaps where I misunderstand the problem)

It's not about the money this time - but the implications to utility are the same. The 'million dollars' in Newcomb's problem is allocated in the same way that life is allocated in this problem. In this problem the money is basically irrelevant because it is never part of Prometheus' decision. But existence in the world is part of the stakes.

The problem feels different to Newcomb's because the traditional problem was constructed to prompt the intuition 'but one boxers get the money!'. Then the intuition goes ahead and dredges up reasoning strategies (TDT for example) that are able to win the $1,000,000 rather than the the $1,000. But people's intuitions are notoriously baffled by anthropic like situations. No intuition "um, for some reason making the 'rational choice' is making me worse off" is prompted and so they merrily revert to CDT and fail.

Another way to look at that many people find helpful when considering standard Newcomb's it is that you don't know whether you are the actual person or the simulated person (or reasoning) that is occurring when Omega/Prometheus is allocating $1,000,000/life.

If consistent decision making strategy is applied for both Newcomb's and this problem then those who one box Newcomb's but two box in this problem are making the same intuitive mistake as those who think Quantum Suicide is a good idea based off MWI assumptions.
