Another thing to consider with
PUA material is that as a general skill, seducing women requires learning concepts that are for many people "non intuitive truths". For example the idea that a women would be more attracted to someone who teases them and disagrees with them rather than someone who goes out of their way to be be nice polite and agree with everything they say, is not something that the vast majority of men would discover on their own.
Its interesting as I see parallels with my day job, which is coaching software development teams. I have to persuade people that (among other things) two people working on the same bit of code at the same computer is more productive than them both working on different things separately.
