In addition you are misquoting the definition of a noun adjunct. A noun adjunct is a noun acting as an adjective. It does not join together with the other noun to make a new noun. What you are describing is a compound noun, as in shoeshine, raindrop, etc. These are not nouns adjunct.
A noun adjunct is as I've said, a noun acting as an adjective and describing the other noun, i.e modifying it or differentiating it from other types of that noun, as in theft of cars, and other types of theft.
So that is the second reason why the word "aggravated "does not apply to the "theft of cars".
Your use of closed compound nouns such as raindrop is very slippery. But I can see why you tried to slip it in to confuse matters.
So, let's stick with a proper example such as 'coffee cup'. You accepted that this a compound noun where 'coffee' is the noun adjunct. And you have already accepted that, in my example sentence, the adjective 'new' applied to this compound noun:
'We bought new plates and coffee cups'.
So, it seems that you agree with me regarding the basic principle.
I take note of what the Court of Appeal said in relation to the construction of contracts.
The rest of your post is confusing waffle.
