The CD standard as the "Joe Average" is quickly changing. Anecdotally, as a younger person (recent college grad), people my age don't buy CDs out of necessity nearly as much anymore as they used to. We've gotten to the point where the vast majority of devices (car stereos, home systems, etc) have at the very least, an aux port. Adding on to this, the prevalence of phones as speakers and music players means that you hardly every "need" a CD. CDs are quickly going the way of records and cassettes.

We can see this pretty clearly looking at consumer reports[1], where you'll find that vinyls, compared to CDs, are actually being propped up largely by generations (18-44) that never properly experienced them. CD usage, on the other hand, is generally supported by older generations that are slower to adapt to modern streaming. Vinyl is almost vicarious nostalgia- most vinyl users I know (generally from the same age bracket) enjoy it as a deprecated technology that feels exotic. CDs aren't necessary for us anymore, and since we grew up with them, they aren't as enchanting and romanticized as vinyl.

In this analogy 'new cars' (CDs) have already largely been antiquated by the new technology of personal teleportation (audio files distributed over networks.)

The market for new cars still exists because some people don't like teleportation. Some people worry that teleportation recreates you imperfectly on the other side and thus prefer a new car. But that demographic is shrinking. Teleportation is simply so convienent that the overwhelming majority of consumers think the price worth paying.

Digital recordings still vastly outsell vinyl; it’s just that CDs are declining in favor of MP3s and streaming, whilst demand for vinyl among enthusiasts/collectors holds up.

It would be like - in a world where everyone used Uber, public transport etc - 5 old cars outselling 3 new ones.
