Huh, you can make money by selling your body.
What a brand new invention and revelation.
You don't have to sell your body. Some girls are being paid $20 for merely texting "I love you" daily to some men.
Others are merely sleeping in front of the camera or doing random shizzat.
Her experience doesn't account for the experience of all women. Hers is the privilege accompanied with physical beauty, not with just having a vagina.
This is like saying "men have it easy" and showing a video of Ryan Reynolds or the superman/witcher actor to make the argument.
Also, the problem here are simps, and the media that pushes them into their simping habits, not some woman realizing she can control the spending habits of losers.
One more thing, she better invests that money because those tits won't last forever.
Plenty of average and even below average looking girls have gotten a ton of money. In fact when a girl looks below average many guys think "no one will hit on her, I've more of a chance".
Looks do sell, and halo effect is powerful. But in general average looking girl has it easier than average looking guy. Also even in relations or marriage she can drop sex out of the relation, out of the equation, and still get money, and if guy doesn't like it he can be taken to the cleaners.
Guys will date and marry a girl even if she's asexual, or has trauma or is disabled in a way she can't have sex.
That said you're correct and not all manage to profit, despite it being easy, and despite some counselors saying most girls are asking about onlyfans instead of college. In general girls have even used tinder to get guys to come and fix their cars in the middle of nowhere. The amount of men who haven't had sex in a long while is increasing, and simping knows no end. Also look at waifu vtubers, they are not selling their bodies yet making decent sums(if I'm not mistaken), and their physical appearance doesn't matter since they have anime appearance.
A girl can get a ton of simps or a lone simp, even without giving sex as happens in many cases, and get a ton of money. Sexless relations do exist.
