We can evolve while also avoiding harmful things. Environmental regulation has made life better for a lot of people and so would a reduction in light pollution.
I think that sound pollution is more harmful. But it is just me, I like seeing that there is a life in the city at night. I can cover my windows if it bugs me, but I insulating my home more against loud sounds is quite hard and much more costly.
You can block out light, but you can't regain the sky that way.
Sound attenuates much faster. If you live in the SF bay area and want to spend some time without sound pollution you can do so easily. Many of our open space preserves are noted for their level of quiet.
I chose where I live partially on the basis that it's extremely quiet.
If you would like to experience an extremely dark sky, however, you'll have to drive several hours and much of the US can't even get to one in several hours.
