You cannot compare visual impact to impact on ground based cameras.
There's a big part you are missing in all of this. Astronomers cameras are FAR more sensitive than human eyes. What is visible to your eyes and what happens to a camera image are going to be very different things. You might want to research exactly how many will be going across at any given moment because that's roughly how many their cameras will see. Not to mention they are 6 times more reflective than other satellites. Have you seen the difference between a milky way image taken as a long exposure and what you can visually see with your eyes at a dark location? That's the kind of difference we are talking about here.
