That seems to be somewhat of a myth.

You can not only buy music on physical medium (CDs or vinyls) but you can also buy, legally, DRM-free lossless music.
And once you own that music, your right to listen to it (privately) cannot be removed from you.
And for, say, a vinyl or a CD, both in the US and in the EU, your right, for example, to sell that CD at a garage sale cannot be removed from you.
And just as I can, today, boot a Commodore 64 from the 80s, I'll still be able, in 40 years, to boot a Raspberry Pi and play my music files from it. And play my CDs if I've still got a reader.
P.S: FWIW I rip my audio CDs to lossless files, in a bit-perfect way (which is automatically cross-checked with checksums of people who made the same rips, so we all know our rips are bit-perfect).
I can still go to the store and buy some music on physical media, and (if history is any indicator) I can still play it forever until it or my playback equipment wears out.
As a practical matter: You do know that when I spin up an album at home, I simply do not care what limitations any licensing agreements may or may not apply, right? I'm going to play it anyway, and it will work when I play it -- free from outside influence.
