I think you're underestimating the difficulty, even for exact copies of text (which AI mostly isn't doing).
What sort of Orwellian anti-cheat system would prevent copy and paste from working? What sort of law would mandate that? There are elaborate systems preventing people from copying video but they still have an analog hole.
Of course, we’d need a significant change of direction in leadership, but it’s happened many times before. French Revolution seems highly relevant
