When a robot replaces your job (or perhaps your friends or family) and you/they lose their way of earning money will your argument remain the same?
If AI/robots could give us the utopia from sci-fi books it’d be grand and I’d be inclined to agree with you. But they aren’t, no one is getting early retirement because a robot replaced them in a factory and artists aren’t getting residuals from the derivatives these “trainings” are creating. It’s theft, outright, and the thieves are trying to make money off these originals.
