Fame has a very short half-life and unless you have all the licensing/contractual machinery in place beforehand, you probably won't be able to cash on that boost. The line of thinking you articulate here is extremely familiar to anyone who does creative work. It's the same argument that producers use to get people to work for free or cheap on films, that broadcast or streaming services use to justify very low payouts to content creators, that commercial commissioners use to try and get art for free etc. The creative field is absolutely full of promoters who offer to match artist to audience, with the promoters getting the first cut of ticket sales and the artist getting the last or none.

Besides, attribution is naturally built into those "plagiarist" prompts for AI.
Only if you are already kinda famous. Suppose you have a distinctive visual style that's a great fit with a genre, like ghost stories. I, an unscrupulous publisher, note that the market for ghost stories is currently booming and decide to buy, or perhaps generate from AI, and bunch of mediocre ghost stories, and then publish them with 'art in the style of scotty79.' I make a little app offering 'best new ghost stories every day!!' for $1, put it in app stores, and make $7 million before the ghost story fad runs its course. You get nothing, and consumers who got familiar with your style by paying $1 or looking at ads to use my app don't care about you because I never gave you credit and in their mind the style is associated with Best Daily Ghost Stories, not you.
Maybe a few of them will do the work of combing back through the history of the fad and to find which artists influenced the 'daily ghost story' aesthetic. Maybe this will lead to a revival of interest in your work even though the fad it was associated with has come and gone. Good luck with that.
The dirty secret of the creative industries is that if you don't get paid up front for your contribution, you will probably never get paid at all.
