I understand your standpoint. I feel pretty frustrated with these questions too - especially when people throw large assumptions around like panpsychism. However, I gotta disagree with the idea notion that no qualities exist in the universe. Afterall, isn't every single thing a part of the universe, including thoughts, feelings, and experience?
Here is a thought experiement:
Think about experiencing pain and what it feels like to you. Really try to simulate it in your thoughts. Probably sucks. Now think about happiness and what that feels like to you. Probably doesn't suck as much. Without watching a scan of your brain, and without collecting any sort of scientific data about your nervous system, you were most likely able to discern the difference between those two feelings just now. You didn't do this by any type of measurement of quantity, just by quality of experience (qualia).
So I would argue that either quality definitely exists, or everyone reading this just experienced something that is extra-universal, which in my opinion is just as fantastic and assumptive as panpsychism.
Also, I am not a theoretical physicist nor do I have half of a firm understanding of even classical physics, but apparently there has been advances in theoretical physics to include consciousness into the same theory as quantum and classical physics.
