I wouldn't call it "tortured logic", all his points are valid. Of course, there are ways you can listen to headphones 8 hours a day without getting hearing loss, and there is music you can listen to that isn't distracting or imparing your cognitive function, and there are a lot of people that are perfectly fine sitting in a room with a bunch of other people that they can't see or hear, but I think these are valid issues that at least some people that wear headphones in open offices might encounter.
