With traditional adult entertainment, creators are aware of the social ramifications (e.g., social stigma, familial ostracism, difficulty dealing with the future, and so on), and there is a decent theoretical economic framework to measure that.
I am not sure if there's the same this new army of "civilians" joining OF, let alone the additional toll it will take on the creators in terms of social ostracism, future prospects, future opportunities, and mental health.
A few decades ago, there weren't that many "productions", performers were much fewer and some porn performers name were known by anyone, regardless if you had seen porn with them staring or not. A person getting out of the business and trying to make a new career would have a high chance of meeting people, especially men, in real life who might have seen at least one movie.
Nowadays pornhub and onlyfans are flooded by wannabee independent performers. Even the most addicted to porn can't possibly follow and keep track of more than a tiny subset of performers. So there is a good chance you can still have a career alongside it or switch from OF to a non sex related career easily.
Your model of "social ramifications" seems to assume no one ever talks to anyone else, which is dead wrong. So to see problems, the only thing that needs to happen is one person needs to see their porn out of maybe the 1000 people who could recognize the performer IRL, then a rumor starts and a significant fraction of the 1000 (and more people besides) find out. No fame required.
Then the problem can balloon if another person out of that 1000 is angry with the performer, and decides to dox them by creating a website or posting that explicitly outs them to anyone who searches their name on Google.
Then, on top of that, there's all the facial recognition tech that's floating around, which is basically a "go strait to jail, to not pass go" thing.
