Honestly don't even know how to feel about this regulation. I think in principle I like it. If one uses AI to generate content on a topic and is not actually checking its accuracy, why not force them to label it.

What practical benefits this might have in the long term I do not know. Perhaps an implicit trust in orgs/individuals who actively tag AI-generated content.

If one is known to tag AI-generated things as AI-generated, the un-tagged things have more weight as being original. To be honest I don't think this is a likely outcome.
