Not to forget anyone below them. Aviation is one of the fields which can affect others in lot more than just immediate surrounding area. I don't live under much of flight path but still dropping planes and even parts of the planes are really not optimal.

It used to be that living next to an airport was hell due to noise even without supersonic jets. Then they regulated noise levels and magically airplane companies started to find ways to mitigate noise levels. Such a coincidence that suddenly innovation just happened then and not ealirer. Who can guess why.

The industry was allowed to develop, but not allowed to cause harm.

So basically "if they were only allowed to cause harm then maybe maybe one day they might have found a way to on their own for no profit stop doing that harm"? Yeah, no thank you. Also, all of corporate history shows that without a government or public pushback "will stop doing harm" never happens.
