If it isn’t economically viable, it shouldn’t exist.
If you’re claiming this as an axiom, I disagree. Public transit isn’t economically viable. Homeless shelters and soup kitchens aren’t economically viable. Increasingly in the modern world unbiased news isn’t economically viable. If you’re handicapped in some way you’re probably not economically viable. Honestly the human race isn’t really economically viable. Some things are objectively good and should exist at any price.
Now, I’m not under any delusion that Spotify is one of those things. Lol nope. But the statement on its own isn’t really a defensible one, and I think only the most strident Randian libertarians would try.
If you’re not claiming this as an axiom, and just saying that if Spotify in particular isn’t economically viable it shouldn’t exist, then I can probably get on board with that. But for my family’s mental health, I think a service like Spotify should. Or the return of a plurality of online mp3 storefronts.
