If there are no real worlds, but only BBs all along, this argument doesn’t work.
However, it is still not a big problem, as Dust theory still works, and for any BB there will be another BB which represent its next mental state. So from inside it will look like normal world. Mueller wrote a mathematical formalism for this.
Oh yes, ‘real’ is a fuzzy concept once you allow Boltzmann/Dust approaches. Things just… are, and can be represented by other things that also just are...

In his article Mueller says that no physics exists at all. Only math world exists, and dust minds are just random strings of digits.
And strings/digits themselves are just a bunch of bits in fancy clothes.
At some point, years ago, I decided that reality was basically just ‘nothing’, endlessly abstracted, and what can you do? :_D
