I don't think that's enough. Particle interactions are unitary, but measurement looks non-unitary from the point of view of the observer.

Reality is intersubjective, but not subjectivist.

I think confusion arises when people hear 'measurement' and jump to thinking "wait, what's so special about measurement? Would the world not exist if we weren't there to measure it?" This is due to an imprecise understanding of measurement, and should be corrected by pointing out all particle interactions are measurements. Our classical world exists without superposition because there are enough particles interacting with each other that everything is constantly being measured.

I cannot agree with this more. Universe has been existing without intelligent observers for billions of years. It stands to reason that universe is constantly being shaped as particles interact.
