I am learning here that space-time is unreal in the sense that a photon for example is "real". Maybe I'm saying the same thing you are (along with Kant). I would put it like this:
The quantum "wierdness" they're talking about where "it's not there unless you look" (as an example) isn't all that weird. This is how our minds work! This is how our memory works. It makes no sense to ask "where" the memory has been stored in space. It's not.* But if you want to you'll find it with some probability. Superposition: taste, smell touch etc simultaneously activating a mind set. Sure we can think of lots of examples how this works.

*It could be argued that the chemical basis of memory is stored in spacetime. Cause and effect is a slippery subject in philosophy. In the quantum cause and effect breaks down. Pattern correspondence is an interesting substitute.
