Probably not. Copies of bokov are pretty rare in the universe (one every 10^(10^29) meters), but copies of bokov together with a correct copy of the whole observable universe have got to be vastly rarer. Only one out of every (insanely huge number) would see the same night sky you do.

Since someone who has read that Tau Ceti is in a different location than I read it is will no longer be identical to me, can I make myself unique by learning a lot of astronomy?

Or are most bokovs merely similar and only occupy identical configurations by mistake, e.g. by misreading information in the same way? But wouldn't we each still be entangled with enormous numbers of objects that are entangled with the true locations of our respective stars called Tau Ceti?

If we restrict our attention to identical bokovs living on relatively earth-like, or at least life supporting worlds, what generally happens is that on some planet an atom-by-atom identical copy of you suddenly spontaneously materializes (due to quantum/thermal noise). The first thing this copy will notice is that it seems to be somewhere other than it was before, since it has your memories: the last thing it remembers is sitting down reading this site. Then, if it's night time, it will notice that the stars are in completely wrong places and eventually become very different to the bokov here as it gets used to living on the alien world.

ETA: Yeah, as with boltzmann brains, actually the majority of patterns identifiable as bokov will be manifested in very bad places to live, like in space, in stars or oceans. And they will immediately die, or be reduced to random particles again in the case of a bokov formed inside a star.

And if we don't restrict our attention in this manner, this number is dwarfed by the number of bokovs being spawned inside gas giants and stars. Which are in turn dwarfed by random blobs of particles containing random bokov body parts spawning.

So your answer to the question of subjective expectation is "never mind red room or green room, you should expect to wake up boiling alive and/or freezing while gasping for air and clutching at the spot you legs used to be".

But by that logic, given that so far I have not been, I should assign this explanation a very low posterior probability.

Well, no, while the existence of the boltzmann bokovs is intuitively obvious to me, I currently prefer to keep an open mind regarding if and how that matters for subjective expectation.
