That is an example of the absurdity of this argument I'm criticising. Paul is telling people they don't need to circumcise their sons or obey dietary laws. A number of ordinary adherents of the James movement object to this abandonment of normal Jewish customs.I think the point is that James people, the Essenes, the Sicarii and the Jewish populace in general were a movement against the Romans and their Herodian puppets. Paul and his followers like Manachem/Manaen, Simeon Niger etc were firmly on the side of Rome and Herod.
I'm not sure why you think it is so untenable that the followers of James left behind the DSS. They (James & co) were famously "Zealous for the Law":

Just to give one example.
Therefore they wrote the DSS? That's crackers. It simply means they were observant Jews, objecting to a teacher promoting inordinate laxity.
