The idea behind green screen is to replace the green background with one of your choosing. Just how would the camera, in your idea, get rid of whatever is behind your subject when recording? How would it know what to rotoscope out? and how much horse power would that camera need to be able to do that on the fly?

short answer: it wouldn’t.
