"no other form of entropy"?   See examples in this thread.
So where does one get entropy if not the ethernet adapter on many
embedded systems?  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.
