What you suggest is not the classic office experience. It's an experience that is inferior to WinWord 1 from 1991 out of the box. You're suggesting users spend *hours* reconfiguring the UI to a state worse than a version that shipped 23 years ago. They would have to do this on every computer they use. Assuming a computer at work, a computer at home,a child's computer, a laptop, and a friends computer they are helping them with, that's a week configuring toolbars.
