the fact that two different situations of uncertainty over true states lead to the same physical predictions isn’t obviously a reason to reject that type of view regarding what is real.
Sorry, I meant to add: in Einstein’s version, the problem is that which of the two “situations of uncertainty” is the right one to talk about could depend on what someone does to another quantum system light-years away. And therefore, nature is going to have to propagate updates about what’s “really real” faster than the speed of light.
