If you have no mouse, no keyboard, no hardware number generator, just ethernet ports and a serial console that usually receives no input. While ethernet might not be preferable if you have something else, sometimes you really don't have anything else.
Already answered in this thread... EGD illustrates how many sources of entropy remain, even in the example you just gave.
Further, you do not want to rely on entropy from a source that declines just as network traffic increases.
