No kid wants to fuck an old man, and I don't see how you could legalize brothels or prostitution for minors.
It's about power a lot of the time. Wealth gets you anything you want, so anyone with enough money who wants to abuse kids, can. I'd imagine some extremely wealthy idiots are tricked into it for blackmail on rare occasions.
Organizations, like the church, attract pedophiles because it's a trusted position of power that puts them alone with vulnerable kids.
No, I don't think indulging in child abuse is something a regular person does, even if they have urges to. You're not a regular person if you're abusing kids.
