Your arguments are from the PoV of the wearer. Sure, as a wearer, you know that you are paying attention to whoever you are talking to, but as someone on the other side, I don't know that. That's not a problem with sunglasses because it's inherently impossible for you to be doing something else. The issue that people have with AR glasses (and to some extent, people wearing sunglasses unnecessarily) is that AR glass wearers are thinking more about themselves than the perspective of other person. And then to defend AR glasses saying "I could be doing something important but actually I'm paying attention" is like doubling down on that lack of awareness. I'm not opposed to AR glassses. I'm just explaining why they are a bit of a faux pas and the people who think they are OK are also the reason why they are not OK.
