I am a bit behind in my digest, so maybe someone has already said this.

True, carbon is a basic building block of the universe, but then again so is
sodium.  A sodium print would last but a few moments in a humid environment.
It is a reactivity thing, not a basic building block thing.  The atoms of
sodium, carbon or platinum will not be destroyed, but they might meet
something that likes them better in a different form (if I might speak
anthropomorphically like I do to my students sometime) and that would be the
end of your print.

Do I know the answer to the initial question?  No.  But just because carbon
is a basic building block doesn't really answer the question, either.
