I don’t think you should penalize Boltzmann brains or Earths (or sapient species) based on which particular one you are looking at.
But presumably you could also specify a recipe that eventually produces a BB.
I think the point of it being a Boltzmann brain is that there is no recipe. It’s just a random fluctuation. If there were a recipe, there would be time-consistency and it wouldn’t be a Boltzmann brain.
Any given configuration of the universe either eventually will produce a BB, or won’t.
Because BBs are much smaller than Earth, the number of configurations that eventually lead to BBs should be much larger than the number that eventually lead to Earths, and therefore the number of variables you need to control to ensure you eventually get a BB should (in expectation) be much smaller than the number of variables you need to control to ensure you eventually get an Earth. BBs are a larger target in possibility space, and therefore (in expectation) easier to hit.
How is that different from saying that you do not have an Earth unless you can point to it? If we require that you augment the recipe with some spacetime coordinates that tell you where in the resulting universe to look, why are those coordinates any longer for a BB than for an Earth?
To point to a BB that has the same experiences as a human, you need to go really far into the future. You essentially have to hardcode every bit of those experiences, none of it comes for free.
For a human on Earth, you get the order somewhat cheaply.
Compare two Earth humans, where one is like you, and the other introduces a bunch of ad-hoc changes. The changes reduce the amount of order in its experiences, which increases the complexity of the program. The fact that the experiences are less complex is what it means for them to be ordered.
Now suppose you have a BB that “cheats” a bit by coding in some of the order to reduce complexity. Instead of hardcoding a memory of the sun rising every day or whatever, it codes it once and copies it, to save some bits. Well then the prediction it makes for the future is also ordered! In order to get a “pure” BB that produces total randomness for the future predictions, you need to hardcode all of the order in the past and not use it to cheapen your complexity.

“eventually lead to a BB” is not the same as “locate a BB”
you do not have a BB unless you can point to it

time is a coordinate
you’re taking the word “coordinates” too literally
also I’m not engaging any further, you’re pissing me off
