Yet you participate in society! Curious.

One persons "improvement of society" may be the opposite for another person. And if you share a small space (a city) with a lot of other people, you have to take that into account. Our physical world isn't the Arch Linux terminal, where a hacker is omnipotent and everything bends to his will. We have to take other people into consideration. And then the goal of reducing noise levels start to interfere with other important things, such as public transport, goods delivery, the ability for people to work, etc.
