"cable manufacturers don’t required to include measurements to sell cables and it will still perform as intended. "
Yes they are required to present measurement data. If you buy a data cable on amazon or a pair speaker cables from some major brand like Cardas Kimber (they'r not manufacturers) typically you won't get the data sheet. But when Cardas buys their audio cables (bulk) from cable manufacturers like National Wire/Cable, one of few good American factories, or buy data cables from Sinotek China their cables must come with data sheets that include Construction Details (conductor/insulation/shield/outer jacket), Electrical Characteristics (impedance/ capacitance/propagation velocity/max. current/voltage rating/temp range, etc..
I agree that the analogy wasn't a good one. Yes cables do make a difference I don't deny that... but don't have to be stupidly expensive to be an excellent one. oh and what about that snake oil lamp sitting on the cable practically doing nothing.
