That would depend entirely on her circumstances. Is she a professional helping disabled people like my example above? That's laudable. A self-employed dominatrix with a select clientele? Sounds lucrative. A popular OnlyFans starlet just making some money on the side during her studies? Clever. Participating in explicit forms of BDSM porn? If she does so of her own volition, with the consent of all parties involved, for a fair pay and without lasting harm? Cool as long as she's working with professionals with a good reputation.

In all of those cases I would council her to the best of my abilities on safety and long-term planning, if she'd let me. And of course, as any parent, I would worry about her safety. But hey, I'd worry if she went paragliding or mountain climbing too.

Honestly, I would be more disappointed if she became a lawyer in the pocket of, say, Amazon or AirBnB. Or a politician for some extreme right political party.

Would I be happy if she was a sex worker in some seedy part of town with a pimp hovering over her? Of course not. But that is not dismissive of sex work as such, rather of exploitation and coercion. All of the examples above avoid that.
