I hear you, and fair questions, but also a fair amount of effort and ammo by someone to figure all this out.
My a priori theory is there is so little difference in barrel wear between adjustable blocks and non-adjustable blocks as to it not being a valid criterion in block choice.
If restricting the flow at the gas block increases the pressure in the barrel then it will always be still below that of a normal bolt gun with no gas system. And those barrels seem to last just as long as AR barrels that are not abused (i.e. no auto mag dumps).
