What a picture :-)
I don't think so, Dominic.
You are taking the idea of "measurement" too literally.
The analog of "measurement" here is not naive measurement of the components,
it is ordering them one way or another.
In the model of grammar we are talking about one or other grammatical quality
only has sense as a distribution of word associations. The corpus is
objective, but to "measure" grammar you have to group elements of the corpus
together. You cannot do this two ways at once, beyond a constant.
That is true for the position or momentum of a wave-packet also, is it not? It
is the position or momentum of the packet as a whole which is at issue, not
that of its components.
In fact, can you think of waves as having a measureable position at all
without clustering them is some way?
