Bullshit.
I've worked with sex workers. Consequently, I've known scores of them. Some of them really, really well. I've never met one of them that was proud of what they did.
From what I could tell, they tend to go into the business because it's an easy way to make a lot of money. Most of them (but not all) because they had expensive drug habits to support.
None of them would ever want their children to follow them into the trade.
Working in outreach programs with my church, I've run into a few ex-sex workers and all of their stories are the same (at least the ones that entered into the industry voluntarily). Some start out with good intentions of making some money to support their children or maybe their education, but it's never a lifestyle they actually wanted; to them it was sometimes a last resort (which it never is, they just don't know what else would have been available to them). Being in that environment invites abuse, sometimes getting sucked into being trafficked (often without them even realizing it until they try to exit), and exposure to drugs, which it then it's no longer a job with the intention of bettering their situation, but to support their habits. None of them are proud of it and never want that for children, much less other women.
The ones that don't regret it are few and far between, like Brandi Love, Nina Hartley, or maybe the super high end escorts. Still, despite being happy with their career choices, I seriously doubt any of them would want their children to follow the same path.
If I was to try and offer the only defense of OnlyFans that I can barely reach for; many of them (definitely not all) are at least their own masters, not beholden to an agency, pimp, club owner (or whatever else). Still, it doesn't excuse the nature of that work, as the emotional trauma they're causing for themselves will still always be present, on top of the dangers of parasocial relationships, the relationship and financial damage they're causing to their paying "fans," and living with the knowledge of how they've degraded themselves.
