A fundamental right to remuneration for your creative work that can’t be signed away is in exactly the same spirit as a fundamental right to privacy that can’t be signed away. In both cases you start with a legal protection that’s good and necessary in some cases, declare it a travesty that people are signing away that right en masse against the EU’s opinion of their best interests, and close the door to that sort of contract. In both cases this flies in the face of established internet customs, so you shrug and say “in a society there must be rules, you can’t escape the law just because you’re on the internet and have gotten used to doing it.”
