This is a fair point, once there is no longer a need for these satellites they will fall out of orbit, self-immolate in the atmosphere, and we can simply not replace them. It's a worthwhile tradeoff, in my opinion, to inconvenience a branch of science that's unlikely in the near term to produce research that immediately benefits humanity. Conversely, projects like Starlink solve an immediate problem (access to communication infrastructure in underdeveloped areas) and are sufficiently designed to account for the eventuality of their purpose expiring. These satellites were never meant to be permanent fixtures in the sky. Astronomers complaining about streaks in the sky seems a bit like a retiree complaining that the new hospital they're building across the lake ruins the view from his kitchen window.
