That's a long paper and I am interested to read it. From what I have heard, there is more adoption of Pearl's methods in Epidemiology and in Social Sciences, in contrast with Econometrics. To me, it reminds me of Dyson Freeman's, "Birds and Frogs". For most Statistician's and Economists Regression is their goto tool and the Potential Outcome Framework is much more natural to them. You could say the same about the synthetic controls methods you mentioned.
