Absolutely not an amateur, and I stick by my post. We are dealing with a wire here. It is a passive element with no phase lead or lag. As a result the impedance and resistance are equal, as the impedance has a phase of 0 degrees.

I have never ever used superposition to perform resistance matching, but I've used it lots of times to calculate matched impedances, even when the impedance was entirely in the real domain. (No inductive or capacitive reactance.)

Oh, please. This has to do with clarity for yourself and others.

When resistance is the issue but you switch to the term impedance, you muddy the waters for others who don't understand the distinct difference between impedance and resistance. You make it appear that they are the same or that you don't understand that they are different. That's why it's an amateur mistake (like my spelling of whoops). They are drastically different, even if the actual reactances in a given situation, such as a power cord, are so small as to be negligible. Negligible means able to be neglected, or ignored, and that's the case with power cords. So, yeah, the impedance might measure identical to the resistance, but they are not interchangeable concepts so one should not be substituted for another in the middle of an example.

As to your last answer,

A capacitor is a passive element, so just being passive is no guarantee of no reactance. I don't even see why you mentioned "passive." Maybe you had a good reason.

You say it has no phase lead or lag. It has no IMPORTANT lead or lag, but what did you get when you measured the phase on your phase meter? You got zero, to how many decimal places? Or you didn't measure it, but assumed? (It's a reasonable assumption, but if assumed, the assumption should be stated or the word "resistance" should be used.) Remember, I was saying resistance is what matters, which is just how you correctly started out. You are the one who has said ZERO regarding reactances.

What we are interested in is resistance because the inductive and capacitive reactances are so tiny that they don't matter. But it is not possible for two parallel wires not to have capacitance -- even, say, 1 pF -- and it is not possible for any wire to have zero inductance. That's zero with a decimal point and infinite zeros after it, meaning really zero.

Your last paragraph is pretty impressive. It shows, though, that you'd rather use fancy words than be clear. This is not a forum for EEs, but for regular folk who are trying to do and to learn. Jumping up into superposition without an explanation is of no help to anyone unless you intend to "prove" your points by showing that you can say something that most of us don't understand, ergo (more like ergot, really) you must be right.
