(and don't tell me everybody uses Amazon Prime day shipping... people just order new cables when they break. And sure, you can have one common pool of all your cables... sort of! except for the part where cable X or charger X doesn't fast-charge device Y, so you actually need several pools of chargers and cables...)
Failures due to "user error" are still failures that induce cable replacement, and a cable that you interact with less (because it's running to a fixed wireless charger stand/pad) is less likely to have user error failure modes like that. Wireless connection or wireless charging (built into the car, f.ex) removes these modes entirely - you can't break an aux cable that doesn't exist.
You can't just assume "nobody ever breaks a cable" as being a realistic proposition when looking at the lifecycle of these products - I'm not sure I believe you in the first place that you've never broken a cable in 12 years but that's certainly not realistic for the population as a whole.
