Space and time are so intimate to everything we experience that it is hard for us to wrap our heads around a physics that does not localize events to points.
I went through a process not quite as deep as yours and came to the conclusion that for all practical (pragmatic) purposes spacetime is real. Everything we can measure must have a time and place or affect something in time and space or we can't perform a measurement. If we can't measure, we can't test and we can only speculate.
Thanks for reading. I certainly agree with you, but there is a subtle distinction in the question being asked here. It is not "is spacetime real?" but "is holographic spacetime real?" The idea is to ask whether a spacetime that emerges from the AdS/CFT (QG/QFT) theory can be considered real. The philosophical necessity of answering that question is to justify whether theories of emergent spacetime are true or merely mathematical games.
