Why do photographers like to see fron the camera peephole rather than from the liveview mode?

Looking through the viewfinder I have a much steadier hand holding the camera. My viewfinder shows shutter speed, aperture, and ISO. I can see the picture better because there is no interference by sun light. I would have to put on my reading gles to see live view but the viewfinder has an adjustable diopter for my crappy eyes. My camera is on the heavy side and to hold out in front of me to see live view wouldn't allow me to last nine innings.
