So you're being forced to use a workflow you don't like that gimps your productivity, and you still would force guys to use workflows they may not like? That's worse than choosing it man.
Switching workspaces is as easy as moving your eyeballs, at least in a tiling wm. It's no different workflow wise, except it costs hundreds of dollars less. You can literally only look at one monitor at a time. Very, very few people actually have a need for more than one. The majority of people using more than one monitor are doing it because it makes them feel like hackerman, because their boss imposes a workflow and environment on them, or because they can't be bothered to try to make their environment more efficient.
