Am I just being dense, or is this confusing the thing and how we talk about the thing?

Not sure I understand the question? There is an idealization of a perfect resistor; those don’t exist. Actual resistors are nebulous physical objects with imperfectly characterizable behaviors. Whether something counts as a resistor is a matter of social negotiations.

That is just what call "industry standards" and applies to all industries. Tolerance, specs, MTBFs, etc metrics are all worked out by industry groups like IEEE and ASTM and manufacturers test and report those in their datasheets, which customers design against. T'was always thus

Sure, just using resistors as an example because they are boring, so it should be obvious by extension that this is pervasive

Many people think "socially constructed" means "arbitrary" and get all reactionary.

Yes getting that one sorted out would be a major win.

Just yesterday I was struggling with a particularly nebulous component, the ferrite bead. At the material level it is dead simple, a bit of ceramic and a wire. At first it was simply a rod with a hole in it, you usually slipped out over the lead of a transistor.

Ppl did this, and found that it sometimes helped things to work when you had an oscillation or interference. But beads came in different mechanical sizes, and can be made from different ferrite recipes. Experts said they are good, get an assortment and try them out.
