Yes. There's nothing keeping anyone from buying the music they like even if it's just digital. Music is probably the thing that there's there's the greatest choice between renting and very reasonably buying.
I have a big library which I got in order a couple years ago. But I made the decision that there was no need--at this point--to buy any gaps. I'd just stream and could always buy pretty much anything I wanted at some point if I wanted to. (My interests are mostly very mainstream.)
Unfortunately this isn't true anymore. If you want to buy a song there's beatport and bandcamp but they're missing a ton of music, Amazon Music is only available in a few countries and Google Music doesn't exist anymore. That leaves just iTunes which is a terrible experience and only available on macOS and Windows.
Even if you cart around audio files on 5TB portable drives, or have a drive per key location (home, office, etc) there are advantages to streaming. One less drive I need to maintain.
Losing everything when you unsubscribe is shitty though. I guess that's the choice made.
