I don't know for sure if you're making the case that media piracy is more or less equivalent to AI being trained on stolen material (I may be reading that wrong)- but I'd like to add that media piracy isn't making money on the backs of hard working people and forming a dystopia in which human art is drowned out by machine hallucinations.

In any case I agree that piracy should be legalized, or rather, that we rethink our approach to media availability and challenge the power and wealth of producers.
