> The word is very special to this law as it is the core word defining "Digital Currency":

It may be important to this law, but that doesn't mean that it is used specially (as in, in any but its most contextually-obvious general-use sense) in the law.

I mean, the meaning of "is" is also very important to the meaning of most laws, but is rarely defined in the enactment.

> You can't classify something as digital currency without knowing what value means

True, but that doesn't take a non-standard, law-specific definition.

> or how to measure it.

Untrue -- quantification of value is not relevant to the definition.
