Absolutely. You can definitely still win with women over the long term, with enough persistence and wearing them down, but it DOES have to be completely non-needy. I've heard a few stories from women who've ended up with men this way so I know it exists (haven't met guys personally who've used this approach successfully).
The reason I don't talk about it here is it takes a guy who's both 1) non-needy with the girls he's persisting with and 2) interested enough / naturally flirtatious enough to continue persisting with women without getting attached to them or chasing them over the long haul, and that's a pretty tough mix for guys who are learning to come by.
However, once a guy reaches that point where he is truly not needy or attached to the women he's pursuing and he isn't going to lay there awake at night trying to figure out how to get her, then he's fine to flirt with her whenever he sees her... and eventually land her.
Comes down to the old adage about mastering something: you get good enough, eventually most of the rules stop applying to you.
