>3. Because people can still see the difference. People still claim Apple made the end-all solution when with the retina displays "you couldn't see the pixels".

As it turns out, not being able to make out individual pixels does not mean higher PPI stops adding value. Returns are diminishing, sure, but I sure as hell prefer my text rendered on 500ppi devices compared to 300ppi devices. I agree with you if the comparison is between 500ppi and 300ppi, but anything higher than 400ppi seems like a waste. I could easily distinguish pixels at 300ppi if I looked close enough, but I cannot distinguish individual pixels on an iPhone 6+ screen no matter how hard I try.
