The goal realism section was an argument in the alternative. If you just agree with us that the indifference principle is invalid, then the counting argument fails, and it doesn’t matter what you think about goal realism.
If you think that some form of indifference reasoning still works— in a way that saves the counting argument for scheming— the most plausible view on which that’s true is goal realism combined with Huemer’s restricted indifference principle. We attack goal realism to try to close off that line of reasoning.
