and that in fact the whole process of taxonomy can't get
off the ground without them so doing.
Isn't that the point? Under some definitions of "taxonomy", phylogenetic
nomenclature makes taxonomy _superfluous_ by uncoupling nomenclature from
taxonomy/classification.
In Linnaean nomenclature, we first make neat little boxes of predefined
sizes, stuff everything into them, and then label them. In phylogenetic
nomenclature we tie labels to defined places on the Tree of Life -- no
boxes, no intermediary step.
