It's not just the state.
Women aren't all chaste by Nature. We're only chaste if men put a premium on chastity.
Remove the premium and every halfway-decent looking female ends up with an OnlyFans or a double-digit body count.

Well, that and the pill took away most of the danger sex naturally has. Removing the danger also means people have started trying to reintroduce this danger through other means...
I know many fairly sexual women who would never touch LonelyFans because they understand the real long term costs of it. It's not worth selling your dignity for pennies when all the Lonely money flows to Cardi B, Amouranth, and whatever other celebrity decides to spread for the camera.
