That's exactly the way UK courts are heading, see Getty vs Stability AI. The court ruled that there's no infringment because the model doesn't store exact copies, just derived weights, and therefore when it generates new images those aren't copies of protected works.
That's stupid, these courts are stupid
It should have nothing to do with storing copies it should have to do with what the models can produce. And it's clear they can produce copyrighted works, they've just been tuned so they don't.
That shouldn't satisfy anyone.
