So if it's a concept, but one that cannot be measured or objectively defined, then it loses its functional utility. The group "tankie" is a nebulous but acknowledged group of people that support existing socialist states, ones commonly referred to as "authoritarian" by "non-tankies." Since this is not a measured approach, but instead a principle, this is now a meaningless allegation without someone doing the legwork to prove that unitary worker democracy negatively impacts individual agency beyond any other approach.

To explain the Marxist position, nebulous allegations of "authoritarianism" have no weight because they do not explicitly address distribution of power, class dynamics, etc. All the allegations do is create categories of "authoritarian vs. less/non-authoritarian" that cannot be objectively understood from the allegations alone. This returns us to the idea that "authoritarianism" is meaningless, it isn't a useful term and everyone has different ways of understanding its application to real systems.
