Something tells me stronger IP laws will be drafted by holders of that IP, with little if any regard to the potential for job losses for regular people from AI.

Maybe, but it's better than the current situation with 0 regard for potential job losses for regular people, probably why they're in favor of trying something vs the status quo

Most of the public has jobs based upon IP? While it is probably a bigger share than farming, I doubt that. The actual drivers appear to be a mixture of hysteria, and reflexive anti-corporate sentiment as we see even self-proclaimed leftists going "WTF, I love copyright now!".
