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.
This year, however, I've started working from home a lot. I like it much more than any of the above and generally get so much more done. I can relax and breathe in my own home. Make some tea and sit in the garden when I need to think. My focus, productivity and well being have been through the roof. It also helps that connecting from home saves me an hour's commute each way.
Some things can't be done effectively over VPN (mainly working on Xbox or PS4 specific bugs), but for most tasks it's great.
