> We need laws for agents, specifically that their human-maintainers must be identifiable and are responsible.

This just creates a resource/power hurdle. The hoi polloi will be forced to disclose their connection to various agents. State actors or those with the resources/time to cover their tracks better will simply ignore the law.

I don't really have a better solution, and I think we're seeing the slow collapse of the internet as a useful tool for genuine communication. Even before AI, things like user reviews were highly gamed and astroturfed. I can imagine that this is only going to accelerate. Information on the internet - which was always a little questionable - will become nearly useless as a source of truth.
