That right there is the break, because in the event that is being
simulated, there was communication (the entanglement itself) at the
beginning.

Oh, this part.  Okay, try this:

Have two identical sacks, one with a red ball and one with a blue ball
(or any two other objects, indistinguishable without opening the sacks
but easy to tell apart once the sacks are open).  Keep one sack at
random - perhaps have a random number generator that takes atomic
decay as a seed - but send the other an arbitrary distance away, even
billions of light years.

Then, open the sack you have.  You immediately know what's in the other sack.

Now, the "locality" of the information is somewhat arbitrary.  You are
obviously not changing anything at that far-distant location when you
open the sack.  Does opening your sack cause an event that ripples out
at the speed of light, such that whatever is in the other sack will
retroactively have become the other object by the time you could
arrive to see it?
