What is arcane or exotic about the ability to say:

'Jon says "The sky is blue."' ?

It is the most complex type of statement my 18 month old daughter is able to
make. Literally she recently said: "Grandma say 'Sarah did dat!'" which was
true, or so I say :-)

In any case, the ability to create a reference to something has proven
itself useful in my practical experience.

The reason I have suggested that quotation be implemented in a fragment
identifier syntax is that URI references are how we refer to things on the
web, and a statement is one of the things we might want to refer to.

Quotation is related to query and in the same way as XPath serves as a
simple query language for XML, an RDF path language might serve as a simple
query language for RDF. For example:

?x says "The sky is blue"
