I disagree. If there are both unambiguously permitted and unambiguously unpermitted cases, then there is very much law, even if there is a gray area where reasonable people can disagree with what is allowed and what is permitted.
That's not to say that the ambiguities may not still be problematic, but they don't make the whole structure into "non-law".
