The idea feels like sci-fi because you’re so used to it, imagining ads gone feels like asking to outlaw gravity. But humanity had been free of current forms of advertising for 99.9% of its existence. Word-of-mouth and community networks worked just fine. First-party websites and online communities would now improve on that.

that’s interesting that you mention that - never been there myself or anything, but I did come across reports that the city authorities had relaxed rules on large murals to make up for the lack of advertising, and there’s certainly a lot of pictures of some pretty impressive artworks!
