I think something that most people don’t comprehend is just how HUGE space is. For context, at 550km orbit, the “surface area” of the sphere surrounding the earth is ~601 BILLION square kilometers. Suppose we had 40,000 (double the number of objects larger than a softball we have been tracking) objects up there, in that exact orbit, we would still only have one object every 15 MILLION square miles.
So, while it is a valid concern... until we put up “millions” of items, I think astronomers will be pretty safe. However, orbital debris avoidance... much bigger issue.

Just a nit: the r² increase in surface of a sphere that makes this so much bigger an area to scatter the satellites across also applies to the field of view of telescopes and thus cancels out. Edit: Clarification. The above is only true if having a satellite in the field of view is enough to be a problem.
