I _can_ provide insight.
every once in a while I find somewhere that I can provide some value or insight, whether via editing an answer with a url that's out of date, a comment expanding on the answer, etc... and it seems like I never can.
I don't care to jump through the hurdles to get to that point. I didn't come there to ask a question. I didn't come there to sift through questions to answer.
I came looking for something. I stumbled upon something where I could provide value and was shut down because I have better things to do with my time than to jump through hoops.
It's fine for the power users who want the world to see their rep, or the people trolling for questions regarding their pet projects. It sucks for the casual user.
So, yes, in theory the rep hurdle is quite low. I've just got better things to do with my time. -- Which I already wasted trying to help someone in the first place.
