I agree that CDs are unlikely to generate any nostalgia. I was among that generation who experienced vinyl, eight track, cassette and then CD. And while nostalgia is often cited as an appeal toward vinyl, nostalgia really doesn't draw me to any media.
For me the appeal of CDs is as follows:
1. Real media that I own even if I cancel a streaming account.
2. Inexpensive. The least expensive medium you can own.
3. Extensive selection and availability.
4. Easy to find components to play them.
5. Even low end CDPs sound good and can be used as transports.
6. Can be ripped for all the convenience of streaming.
7. You can dive in deep with CDs with little risk. In other words, you can buy a lot of them for little money, get a good CDP, a great DAC and rip them all onto a HD. And if you decided to be done with CDs tomorrow you're out the cost of the CDP and the CDs. The rest you can still use.
