By secondary effects, do you mean artists would cease to create art? If so, then artists living in the many hundreds of years before copyright existed in law would disagree. Or do you mean there isn't enough music, or film or literature, etc. in the world? Spotify doesn't have an input problem as far as I know.

No the secondary effects would be people no longer having to pay for art. Including corporations like Spotify and Netflix.

Artists would still make art but would have to either have patronage or find an alternative income source to make a living.
