Maybe I am wrong, but I think that amature showing nude body does not require tremendous skill or effort. While other content creators in youtube or patreon such as musicians, teachers, entertainers put tremendous amounts of effort into their efforts - you need skill to play guitar, you need to study and study well for an educative video especially about some hard stuff like programming, maths or biochemistry, you need to be really good to play doom on nightmare difficulty and than usually editing video is really hard and time consuming, some technical videos take monthes to make, like doing crazy stuff like making portable nintendo consoles , redesigning lasers etc . And they do it for free!!! Or they have quite cheap patreon. What do you need to make an amature nude photo/video? Take clothes off, put phone or camera , start posing. Yes it needs some effort and knowledge to organize place, make lights, choose pose, check photoes and edit videos, yes you need some skills and yes you need a decent camera but anyway it is much more easier than making aforementioned musical/educating/gaming content.
So basically women can make videos that they can sell for extreme amounts of money just because there is nudity, showing nude body suddenly is more valuable than high effort technical video just because there are boobs and pussy. I wish I could sell my photoes for such money, but no, I had to get education up to PhD and than work hard to earn money.
Sometimes softcore creators don't do hardcore because they want to increase the price of their new exclusive " I finally show my boobs!!!" or " I show my butthole!!!" and then they sell it for stupidly high money.
