Elephant in the room: how many of these people would prefer it to having a private office ? Strangely, this article/survey/infographic never mentions that option. I'd prefer remote work, too, over sitting in an open floorplan office, but I'd much prefer an actual office to either one. The easy "why" is: despite all the drawbacks, a lot of us will do pretty much anything to get out of an open floorplan.
I come in to the office every day because my wife stays home with our 3 kids. Work from home when home is four people that want your attention doesn't work out very well. The few times I tried it, everyone just got frustrated that I was present but not available.
Maybe in a couple years when the kids are in school working from home will seem appealing. Honestly a ten minute commute and the entire office to myself twice a week isn't half bad.
