You are being unnecessariky rude. I have not forgotten what it says.

There are pairs of physical properties, connected by a Fourier transform, that cannot both be known at once. Therefore each property is, in general, only known to be in a range. And therefore we cannot always compare these properties between different particles.

As for measurement, in the Everett interpretation the values are not known after measurement either. All that is knowable are correlations due to entanglement.

But now we are far afield. You made an a priori statement about physics. Physics is not required to oblige you. My understanding of physics says that it does not. But even if I am wrong, and it currently does oblige you, it is still not required to.

A priori assertions do not have a good history. For an example, look at Kant's assertion that reality must be described by Euclidean geometry. He was not in a position to understand the ways in which he would prove to be wrong.
