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 don't know. For me commute is the most pointlessly wasted time a person could do. And I have played lineage. So as long as your commute is 10 seconds home office beats real any time. At least until we get the whole teleportation thing nailed down.
It depends a lot. When I commuted from Redmond to Seattle, that was just a ridiculous amount of time to fill, and transportation options are limited (bus, car, or a really long bike ride). Now I work seven miles from the house, I ride an electric push scooter (Boosted Rev) or the bicycle. If I decide to whip back into ultra marathon shape, I can run to work. I'm not the type to just take the scooter out for a joy ride, so it gives me the opportunity every day to go for a ride along the river. Probably would not have even purchased the scooter if I had no commute, which means I'd still be driving the car three miles down the road for milk. But now I just take the solar-charged scooter if I need something from the store, et. al.
But that same commute in a car sucks ass, so your point stands.
