Apologies for cutting your post down, saving some room on the response.
Oddly enough the only cable I have ever had fail on me in my lifetime is the Lightening cable (within 1 year warranty period).

Lightbulbs I have had my LED lightbulbs for over 7 years, none have failed me yet (quality).
Those audio standards mainly felt with mobile jack/port standards, no one would expect an RCA cable to be affixed to an MP3 player, phone, etc. It did the job due to physical dimensions limitations, this is different from the present single port USB-C that omitting a few pins would shave mm. Compare that to audio mm jack to the two RCA plugs. Those 1/4 plugs were also ridiculous as those were on large audio receivers, again will not work for a mobile device. Besides people still believe they require the best audio equipment to reproduce sound as they can "hear it all." Majority of the people cannot hear past certain frequencies and those who can or believe they can may be imagining certain frequencies. It's okay if you have the money to burn on a perception, I say go for it.

Absolutely, take good care of your gear, buy durable stuff, then waste is reduced. But if you never need replacement cables, then why does having a single, standardized cable matter at all? You use the cable that came in the box - standard connector on one end, proprietary connector on the other. I don't hear many complaints about external HDDs that come with a non-standard miniature connector - as long as there's a USB connector at one end of the cable, all is fine. This whole, perpetual debate is because it's Apple. If only Apple produced PC clones and ran Android, like everyone else.
Having been so dependent on interconnect cables for so much of my work (dozens or even hundreds of cables to record concerts on location), I learned how to treat them so they wouldn't fail me at the wrong moment. And I still made sure to have spares of every cable type, plus adapters to press other cables into service if necessary. I can tell you war stories... Even if I could have standardized on a single cable type (say, 3-pin XLR-M to XLR-F), I'd still need an assortment of lengths from 1 foot to 100+ feet. I'd carry thick, neoprene-jacketed cables with braided shields for stage use, and used lightweight PVC-jacketed cables with mylar foil shields for gear interconnect by my mixer.
Yeah, I was talking about the big, gross, over-built gear of the past, things are so small now that space savings don't matter as much, right? Yet they do. Last post, you were going on about wasted resources. Now, shaving millimeters or fewer gold-plated pins or copper conductors doesn't matter? It all adds up. A 24-pin/12-wire USB-C cable uses 50% more copper than an 8-pin/8-wire cable (assuming the same current-carrying capacity is required). You have those great, low-power LED lamps around the house - do you leave them on because they use so much less power, or do you still turn 'em off when you leave the room?
The cram-more-stuff-into-the-same-space trend hasn't stopped yet. We wouldn't have iPhones if CPUs were still the size of the old Pentiums and PowerPC G5s. Maybe you weren't around for discrete logic - 4 OR gates on an 14-pin DIP, compared to millions of gates and other components on a much smaller smartphone SOC. While there are plenty here who say, "I'd rather have a bigger MacBook with a bigger battery," they'd gladly take a thinner, lighter MacBook if it
also delivered the battery life they desired.
