We disagree on that, I think the focus on developmental is on the assumption that it's easier to do something about the environment than to reliably treat medically, this is only true because doctors etc. know so little about how to treat it medically. Which in my view is not a good enough reason. I hold the opinion that there are effective ways to treat anxiety medically (Low Dose Naltrexone as an example that works for some) and if those were better known then medical interventions would be more effective.
