I see where you're coming from. We don't have open office, but I still deal with noise pollution; however I don't see the big issue with using headphones. There's health concerns (which can be mitigated), but I don't see any other big problems. And come on, there can always be too much drama. Anyway, I apologise for my tone, I just think it's worth considering.
This can't get enough drama to become recognized as a problem.
