By the way, I may have this wrong but it seems to me your

universe (or multiverse) ...?
I think Bruno is thinking of a tree-like branching "block
multiverse" so there can still be FPI due to the branches.
yes, like in arithmetic.
Otherwise definite, random things have to happen in realizing the
block universe - and Bruno hates random things and he likes
infinities,
Well, let us say that I "hate" only the *assumption* of 3p randomness.
Einstein define insanity by such belief (of course that is not an
argument).
so... But you should read L.S. Schulman's solution to the problem
of randomness. He speculates that within the domain of a state we
can prepare, which is of measure hbar=/=0, there are special states
which are causally connected to *future* states and when we choose a
measurement in the future we are selecting out one of these "special
states".
Is that not already the case in the WM duplication experiment? The
problem is not in the selection, but in a "physical" mechanism making
disappear the realities not selected. They always need to add
something to the equation, be it a guiding potential, boundary
conditions, etc.
