I agree, Roy, but what can we do about it? I had been using "virtual
impedance" to differentiate a voltage to current ratio from an intrinsic
physical impedance. How would you differentiate an intrinsic physical
impedance from a voltage to current ratio?

You can do about it what you like. What I've chosen to do about it is to
try and educate the people who will listen, and ignore those who won't.
I find the concepts perfectly understandable without the need for
additional adjectives.
