Agreed, but what "prevents" it is that making a good keyboard-driven UI takes a lot of taste, extra effort to build it, and it must be revisited any time the UI changes. It's duplicated work.
Ideally all GUIs/TUIs are usable with keyboard and mouse independently.
A good example of this is when you have a fancy keyboard-driven workflow yet you can't even do the most trivial task without placing two hands on your keyboard. Sometimes I just want to reach over and do it with one hand on the trackpad.
