Given that this would be the first ever law with any degree of ambiguity ever created, we should create some type of like... room... maybe call it a "court"... where people could "judge" whether a person fell on the allowable or disallowable end of the spectrum
It's a groundbreaking idea but it might work. And who knows, maybe it's an innovation we could apply to other areas of law in case they also ever need to interact with any ambiguity (which hasn't happened yet, of course).
