I'm not missing that at all. I just don't believe there's something wrong with "women's running." Running isn't the issue. There's no big running to wage war against. There can be things wrong with people without there having to be a "systemic" issue in possible category of the world. Systemic has become a completely meaningless word that only works to suggest others are too stupid to understand the magnitude of the problem but I'm smart enough to see the big picture.
There's no system at work in the Salazar situation that's different from an abusive or manipulative relationship in any other area of life. Sometimes people fail or have mental health crises or treat each other poorly. If you want to talk "systemic," I'm pointing out that the system is working pretty well right now and the sport is THRIVING compared to any time in US history.
Mary Cain is probably the most gifted prep runner since Jim Ryun and I feel for her that she's struggled but I can't fathom applying the issues of the typical women's runner to the most freakishly talented person to ever do it in our country. Alexi Pappas had a horribly traumatic childhood to the extent that I would never criticize her reactions to it but, again, what does that have to do with running? Allie O had talked about her eating disorder beginning (I think) in middle school, long before the running system got its grasp on her. These stories can all have significance in themselves but none of them impress me as some kind of indictment of the state of women's running. I can promise you right now that there will never be a time in any sport where every significant person participating in that sport is happy and healthy. That doesn't mean everything is inherently broken.
I wasn't suggesting we should write flashy articles about the women you listed, but rather that they're examples of the fact that the sport is pretty cool and producing better successes than ever before. Seems more like "systemic successes" than issues to me if we're bandying narratives around.
