"...the observer affects the outcome of the experiment."
This is false. It isn't that observers magically change what they observe. The act of observing requires affecting what is observed. The things passing through the slit have to be measured, and this measuring can only be done by impacting those things. That is what changes the observations, not some magical power of gaze.
I am bereft of time to comment cogently further, so I hope this is enough to provide a basis for you to reconsider your fallacious conclusions.
