I don’t think Homunq means to refer to preexisting other worlds (which couldn’t be affected by his actions), but to the worlds that will be generated just after his decision.
Right, I should have been clearer. What I meant is that s/he is privileging one aspect of MWI from unimaginably many, and I simply pointed out another one just as valid, but one that s/he overlooked. Once you start speculating about the structure of Many Worlds, you can come up with as many points and counterpoints as you like, all on the same footing (of the same complexity).
I don’t think I had overlooked the point you brought up: I said ”...naively speaking it seems that [MWI] should be something more akin to 3^^^3 (or googolplex) than to 3^^^^3. So the problem may still exist...”
As to the idea that everything is just a hopeless mess once you bring MWI into it: that may indeed be a reason that this entire discussion is irresolvable and pointless, or it may be that the “MWI” factors precisely balance out on either side of the argument; but there’s no reason to assume that either of those is true until you’ve explored the issue carefully.
