You're getting a lossless PCM copy of the music, and you're getting it as a physical object that cannot be taken away from you except by force. You can copy and convert it whenever and however you like.
I rip my CDs once on a Linux for a FLAC copy I can convert to Vorbis as needed for my Android and Sansa devices, and again on a Mac for an ALAC copy iTunes can convert to AAC as needed for my iPod and iOS devices. And if I need an MP3 to share something with a friend, I can make that too, and I can decide if I send them 128k or 320k.
It's worth the hassle of paying more up front one time, to get an object you physically own, that you rip yourself into a digital library you control, that doesn't stop playing if your internet goes out nor rack up a cellular data bill, in order to not have to subscribe to multiple streaming services to make sure you can listen to all the music you like as the licenses change hands amongus them.
And if you don't have the space or time or spoons to do this yourself, you can ask around with your music and data hoarder friends. Surely someone can hook you up.
If you wouldn't go through all this trouble for its intrinsic value, you can at least do it to not give any more money to all the labels and streaming services deciding when and how and under what stipulations you're allowed to enjoy music.
nearly every CD you see here was purchased for $5 or less. many were less than a dollar, or even free. perfect audio can be yours for practically nothing.
hell, I can probably name each CD I paid more than $5 for.
• Pigface - A New High In Low and The Best Of Pigface: I think $8 each? not bad for double albums
• Skinny Puppy - Too Dark Park and Last Rights: $6 and $7 each, both new in shrink.
• Nine Inch Nails - Hesitation Marks (Deluxe Edition): I think like $6?
• Death Grips - The Money Store: a staggering $11, the most I've ever spent on a CD.
there will come a day when all of your playlists, albums, et al. are unceremoniously stripped from you without recourse. your "saved" music isn't safe, either - once those authentication servers go offline, all of those DRM-encrypted audio files will almost certainly become irrecoverable digital noise. so have fun with that.
EDIT: apparently the DRM that a few services use actually has been blown open (@lexi says deezer, tidal, and qobuz have been trivialized) so you may be in luck on that front
