Property should be protected by law so that people are not deprived of it, but it does not follow that owning property gives you the right to be capricious.
It is a good argument, but it does not apply. Their complaint is about the increased noise-level, which, as far as humans go, we can agree it can become bothersome. We typically disagree over how much and when is too much, but noise absolutely affects property values and potential resale. Take me for example, I did not purchase a place by highway. Extreme example, but same principle applies.
