Could this disordering of locality serve to explain the quantum nonlocality inherent in entangled particles? I believe the answer is yes, and indeed we have shown that this is the case in two different models of fundamental completions of quantum mechanics.

The Final Illusion

The intuitive idea that objects influence each other because they’re in physical proximity is soon to become another of those beliefs that turn out to be wrong when we look deeper

Many of the great advances in science are marked by the discovery that an aspect of nature we thought was fundamental is actually an illusion, due to the coarseness of our sensory perceptions. Thus, air and water appear to us to be continuous fluids, but we discover on deeper experiment that they are made of atoms. The Earth appears to us motionless, but a deeper understanding teaches us that it moves relative to the sun and the galaxy.

One persistent illusion is that physical objects only interact with other objects they are close to. This is called the principle of locality. We can express this more precisely by the law that the strengths of forces between any two objects falls off quickly—at least by some power of the distance between them. This can be explained by positing that the bodies do not interact directly, but only through the mediation of a field, such as an electromagnetic field, which propagates from one body to the other. Fields spread out as they propagate, with the field lines covering a constantly greater area—providing a natural explanation for the laws that say the forces between charges and masses fall off like the square of the distance between them.

Locality is an aspect of an even more compelling illusion: that we exist within an absolute space, with respect to which we mark our positions as we move “through” it. Thus, Newton opined that motion is ultimately defined as change of position with respect to absolute space. If this seems obscure—because no measurement can establish a relation of a physical object to this imagined absolute space—Newton assured us that absolute space is seen by God, making your location relative to it an aspect of the divinity of the world. We humans must make do with relative positions and motions—which are defined relative to physical objects we can see.
