Starters - it is very rare to see that attractive woman standing by herself...even if she is, it takes some plucking up of courage to march on over and introduce yourself. Cheeseball lines or not, we all know that to be true, and we have all felt it. A big part of what the PUA dudes teach is getting over that and teaching that 'she wont bite'. In that regard it is just a numbers game about plucking up the courage. You could make a point that we should all have learned that shit growing up, and you are probably right, but at the same time, we all know the feeling.
That's the thing. They don't teach guys that girls don't bite. If that was the only thing they taught, guys wouldn't be learning the techniques and bullshit they teach. Think about it. If you knew girls didn't bite, would you dedicate a large part of your day worrying about the proper opener? Probably not.
More likely however she is there with 2-3 friends, and often with a male in the group. This is another dynamic - and it is totally a social situation that you are walking into cold - and again, these guys have developed their systems for dealing with that.
They have a system that works no better than introducing yourself and saying hello.
As for the talking and listening - again - is there anyone who has NEVER hit the wall in a conversation with a woman?
Guys that hit that wall do so because they are not sharing thir experiences and thoughts as freely as regular people do when they're metting eachother. It all boils down to fear. If guys didn't put so much pressure on themsleves to be slick, they'd have tons and tons of shit to talk about.
I remember first year at university in Australia sitting in the campus bar with a girl who I knew was into me and just finding myself with absolutely nothing to say. I am generally not particularly socially awkward, but I totally know the feeling. If Strauss et al have a bunch of topics that they know will get chicks chatting - and more importantly, and especially with Strauss - noting that self improvement and taking on stuff that makes you a more interesting person with more to say - helps someone out of that feeling I had in the Flinders Uni Tavern in 1994...then I am all for it
I don't think Strauss et al are any better than regular guys. Their emphasis on mimicking jerk behaviors and attitudes is not something I'd recommend. I believe guys are better off if they just stop being such pussies and talk to women. I know it's not easy to drop pussified behaviors, but they have to confront them sooner or later. It's better to start now instead of waiting the 2 or 3 years necessary to be adequate at these methods.
