"...the probability of observing one particle to be somewhere can depend on where we observe another particle to be, and this remains true no matter how far apart they are."     I think the "no matter how far apart they are" is almost certainly untrue.  Over some distances there must be interaction with spacetime itself, i.e. the metric field, that destroys the entanglement.
