There are two points to make here. The first is that if you want to reintroduce the Start button or the ability to boot to the desktop, there are plenty of ways of doing that right now with third-party programs.

, which performs both those tasks, If your sole reason for resisting Windows 8 is the lack of a Start button, you havenít thought the issue through.
The second point is this. People donít like change, and one of the arguments against Windows 8 in a corporate environment is that training will undoubtedly be needed to ensure that staff can master the nuances of Windows 8. However, merely returning the Start button wonít eliminate the need for that kind of training. Even if thereís a start button, there are still new elements of the interface that will need to be learned: just off the top of my head, features like Charms, left and right swiping (especially on non-touch devices), installing and updating Windows 8 apps and even working out how to power down your machine all require learning new methods.
