  If you accept things like space and time as a given, it is not so hard to see why. When you are measuring many-particle systems the easiest thing to do is measure each particle individually, with detectors that interact with small numbers of them. That privileges the basis that separates out particles over those that we would describe as entangled combinations. Carrying that over to the cat picture requires noting that most of our measurements of the cat, like reflecting photons off of it, interact strongly with individual particles in a way that separates them by spatial location. This takes us back to my original point, which is that although the consequences of space seem mysterious in a perspective so abstract that there is no space, they no longer seem so mysterious when you include other facts about physics, like about particles and fields. I am aware that there are some attempts underway to figure out how space could come about as a consequence of quantum stuff, but even they add extra behavior on top of the postulates of QM in order to plant the seed, so to speak, that spacetime grows from.
