Gonna step outside my usual programming a bit because that light pollution take and a lot of the responses to it aggravated me so much.
No, wanting to see the night sky isn't a twee retvrn to ghibli-ass take. It's not a matter of some anprim impulse to dismantle industrial society for ~nature aesthetics~, it's an extremely visible symptom of environmental degradation that gets downplayed because the externality seems trivial to most people: "Oh no, the night sky, what ever will we do without it."
But it actively disrupts light-sensitive circadian rhythms in plants and wildlife, which disrupts foraging patterns, reproductive and hibernation cycles, and contributes to wildlife population declines. It's not the major contributor to those declines, but it's an additional point of stress in an ecosystem already stressed by climate change and other forms of industrial pollution. And so much of it is wholly unnecessary.
I don't think people realize how far-reaching the problem is, either. That light isn't just confined to the places people use. You don't escape it by just taking the bus to the edge of town. That light carries, in some cases for hundreds of kilometers. Death Valley has some of the darkest skies in the US, and yet, the dome of light above Las Vegas is visible on the horizon over 250 km away! Anywhere within 50 km of a major urban center, just about anywhere in the world, never gets darker than a night under a full moon.
And this is very much a recent problem too. Before the switchover to LEDs, it was relatively expensive to light places. That meant actually accounting for the energy use and making sure it was being used where it was needed. That light was also warm-colored, so it didn't travel as far. With the decreased cost of lighting, it became standard to light places like daytime whenever they might be needed. Lighting didn't get safer, it just got more thoughtless.
The reason you see astronomy-types sounding the alarm most loudly is because they're the ones who have been seeing the full effects of light pollution and its encroachment on dark skies. It's a hobby for me too, but it's partly because I'm a night owl who grew up in a small town with nothing else to do. I used to be able to clearly see the Milky Way horizon to horizon when I grew up in the mid-00s. The last time I visited about five years ago, I could only see it overhead. The population has fallen by like 10%, but the skies are brighter. I can tell when the college decided to leave the football stadium lights overnight. I can tell where the car dealerships that added overnight display lights are. I can even see when trucks with the fuckass LED light bars are coming over a hill from 5 km away.
I'm all for well-lit, safe, and accessible spaces for people to work and play at night. But there is an impact from lighting, and it can and should be regulated like any other point source pollution. It's a pretty straightforward and materialist assessment. But go off about the big scary anprims are coming for your society so people can see the stars I guess, that's not at all a reactionary response to hearing about a problem
