That’s a very strong argument, thanks! You’ve changed my mind! I hadn’t appreciated how big the multiverse in MWI could be, but that’s a good way to think about it.
In terms of what impact this has on my arguments here, I still think it doesn’t affect them, except that I now hope that Ignore-Copies and MWI are not both true at the same time. So in that sense I guess it’s a good thing that they seem to be in conflict with one another!
The mangled worlds hypothesis is also extremely interesting! I hadn’t come across it before, but as derivations of the Born rule go, this reads as the closest thing I’ve seen to the possible approach I was trying to describe at the end of my conclusion, where I speculated on what a derivation of the Born rule that did not clash with Ignore-Copies might look like. I’ll have to go and read Hanson’s papers on that. Thanks again! (may update the post to reference this)
(And if the mangled worlds derivation did turn out to be a way to reconcile Ignore-Copies with MWI, it’s also nice you think it might change the conclusion on nothing mattering as well, so that we still wouldn’t be forced to conclude that!)
