I'll not address your points individually, but instead deal with your final notes. Yes, I believe that every quantum entity may observe and cause wave function collapse _in their subjective view of the universe_. It's easy to believe everything is objectively real whether observed or not because our local views - when compared - are highly correlated/decohered. If you find yourself talking about what it means to observe by breaking down how the eye works, then you're aligned with Wigner's thoughts on it. I am not; an observation in my world is akin to an interaction with. It does not mean "awareness" in the sense that a brain might acknowledge something detected by the eye.
