Well I sure as hell see it! There are at best a 2^(astronomical)
number and at worst an infinite number of states that the universe
could've started at, but superdeterministic fans insist it must've
started in *ONE* and *ONLY ONE *specific state. And why are they
so certain it started in that state? Because that is the *ONE* and
*ONLY*state in which their ridiculous theory works. A theory just
can't get more specific than specifying one thing out of a 2
^(gargantuan) number of things as superdeterminism claims to be
able to do. A theory can't get much stupider either because there
is at best only one chance in 2^(astronomical) and at worst one
chance in infinity of it being correct.
This whole discussion is rather beside the point since the universe is
patently not deterministic.But, if it were, then it
necessarily started out in the exact state that would be obtained if
you took the present state and reversed it back to the beginning. The
fact that there could have been an arbitrarily large number of initial
states is totally irrelevant -- only one numbered ticket wins the
lottery, no matter how many tickets are printed.

And insofar as astronomical improbabilities go it's not really any
different than imagining that we got to here thru a sequence of quantum
branching, each of which had probability less than 1.0 and whose product
must be infinitesimally near zero by now.
What Sabine argues is that in any experiment the preparation of the
measurement instruments (or person) and the thing measured can be
correlated by slower than light signals and so cannot be guaranteed to
be statistically independent. Her idea seems to be that the Hilbert
space could be fractal and this would induce statistical correlations.
