I remember being very confused at school when we were presented with many models of, say, a transistor. It seemed strange that we had to first figure out which model to use. But the idea that you need to pick a model that’s appropriate for the specific thing you are investigating and that a wrong model choice could give erroneous results or worse misleading results was one of the more important things I learned in school.
The DS and most other interesting hardware wouldn’t work at all if we only paid attention to capacitance for capacitors, inductance for inductors, resistance for resistors, etc. We need to choose a model of each capacitor that includes other relevant items, e.g. it’s voltage rating, at least it’s parasitic inductance and series resistance and often it’s parallel resistance and (more often for electrolytic caps) multiple sets of these in parallel. I’m glad I mostly only need to pay attention to frequency, average amperage, expected changes in current for each trace in the circuit board (and the same for each of the traces that that get close to a given trace) in order to properly route it. Wire isn’t just wire - but it’s not magic or rocket science either.
People of good intent that think that LCR is all you need to know about cables will of course think we’re all nuts. But LCR isn’t all that matters with any component let alone cables and I’m not at all convinced that most of the anti cable (etc.) people that show up have good intent.
