At this point, we’re mostly both working with different implicitly-modified versions of the original problem, and so if we really wanted to get anywhere we’d have to be a lot more specific.
My original point was that a factor of MWI in the original problem might be non-negligible, and should have been considered. I am acting as the Devil’s Concern Troll, a position which I claim is useful even though it bears a pretty low burden of proof. I do not deny that there are gaping holes in my argument as it relates to this post (though I think I am on significantly firmer ground if you were facing Galaxy Of Computronium Woman rather than Matrix Lord). But I think that if you look at what you yourself are arguing with the same skeptical eye, you’ll see that it is far from bulletproof.
Admit it: when you read my objection, you knew the conclusion (I am wrong) before you’d fully constructed the argument. That kind of goal-directed thinking is irreplaceable for bridging large gaps. But when it leads you to dismiss factors of 3^^^3 or a googolplex as petty matters, that’s mighty dangerous territory.
For instance, if MWI means someone like you is legion, and the anthropic argument means you are more likely to be that someone rather than a non-MWI simulated pseudo-copy thereof, then you do have a pertinent question to ask the Matrix Lord: “You’re asking me to give you $5, but what if some copies of me do and others don’t?” If it answers, for instance, “I’ve turned off MWI for the duration of this challenge”, then the anthropic improbability of the situation just skyrocketed; not by anything like enough to outweigh the 3^^^^3 threat, but easily by enough to outweigh the improbability that you’re just hallucinating this (or that you’re just a figment of the imagination of the Matrix Lord as it idly considers whether to pose this problem for real, to the real you).
Again: if you look for the weakest, or worse, the most poorly-expressed part of what I’m saying, you can easily knock it down. But it’s better if you steel-man it; I don’t see where the correct response could possibly be “Factor of 3^^^3? Hadn’t considered that exactly, but it’s probably irrelevant, let’s see how.”
On an even more general level, my larger point is that I find that multiplicity (both MWI and Tegmark level 4) is a fruitful inspiration for morals and decision theory; more fruitful, in my experience, than simulations, Omega, Matrix Lords, and GOCW. Note that MWI and TL4, like Omega and GOCW, don’t have to be true or falsifiable in order to be useful as inspiration. My experience includes thinking about these matters more than most, but certainly less than people like Eliezer. Take that as you will.

I think we’re talking past each other, and future discussion will not be productive, so I’m tapping out now.
