*[W]hat structure* would this proposed 'workers state' take.
It's worth reviewing, I think, as to particulars -- in my conception the revolutionary workers would be numerous enough worldwide to kick out current politicians and bureaucrats, to assume such offices for the common good and to collapse others that would then be irrelevant, such as for finance, etc.
The ambiguity is about how a proposed workers administration would function, exactly -- would it be as I just described, or would it be more-institutional, a standing relatively-fixed pool of specialized personnel that do nothing but expedite the administrative tasks resulting from the collectivization of social production -- ?
If it's more the *latter*, then I agree with you that this formulation would be inappropriate because it would be too politically *specialized* and institutionally separatist from all other (regular) kinds of work that go on in the world.
But if it's the *former* (the 'numerous revolutionary workers doing administrative tasks as a component part of their regular work, collectively cooperatively'), then I think *this* kind of 'workers state' would be far more appropriate and valid, a *good* revolutionary-transitional vehicle towards communism).
