I'm a bit over my head int the computer science end of this discussion, but I think Chomsky proved that any language comprised of tokens and syntax is equivalent to any other such language.
But applying this to human language requires omitting much of what language is about.
What Skinner tried to do (and apparently failed) is describe how meaning is tokenized. Rather than start with syntax, he tried to describe the function of language, or why it is we talk.
