Strippers and prostitutes provide a real service, which is scarce and valuable. This is mostly about sex and not feelings.
'Nudes" is not the prime product of OnlyFans, because "hot naked women" is not a scarce product. Love and care is a scarce product for men. It's even scarcer in the age of neo-feminism. So, men get lonely, way lonelier than ever before.
OnlyFans make them believe that they have a connection with the woman, which is far from the truth. Most women usually despise desperate men. It's a business a false hopes and deception, which is not the case of prostitues who provide real sex.
OnlyFans is a business made of contempt for lonely and low status men. I find it unethical, but I'm for freedom, so people are free to participate in it.
