Interesting that the rings of Earth have a Cassini division just like
Saturn's
rings. Upon reading the article, including the reference to Larry Niven's
unstable Ringworld (the instability acknowledged in the sequel "The
Ringworld Engineers"), one does get the impression that little Timmy
Tyler believes the rings are a connected whole rather than particulate dust.

" In the above image, the color purple indicates regions populated
predominantly by ring particles larger than 5 centimeters, while the color
green indicates regions with a significant population of small ring
particles less than even 1 centimeter."

Who needs "real estate" in microgravity?
On second thought, space in equatorial orbit (perhaps based on 1 cm
wide orbital 'channels') *would* make an interesting novelty gift,
like a deed to a square foot of the moon, or naming rights to a star -
one more new way to separate fools from their money.
Imagine the advertising...
"My boy friend just bought me the perfect gift! I now own an earth
orbit! It's at (let me see here) '10,385.28045 kilometers from the
barycenter, plus or minus half a centimeter.' The best part is that
it's tax free because it is outside government jurisdiction."

Organisms still need matter - gravity or zero-gravity.

I hope you realize that a rigid disk cannot maintain an orbit in a
"Rings of Saturn" configuration. It is worse than 'unstable' - it is
'anti-stable' - any disturbance from perfect balance is met with
positive feedback, aggravating the situation.

I hope you realize the rings of Saturn are made up of irregular
clusterings of particles on the order of a few centimeters in
diameter. The clusterings may vary up to several tens of meters wide:

Quote: "At any given time, most particles are going to be in one of
the clumps, but the particles keep moving from clump to clump as
clumps are destroyed and new ones are formed," added Colwell.

You are the only one here concerned with the properties of a rigid
disc.
I can't see why you brought up such an obviously silly idea.

It must have been the use of the term "real estate" in the OP.
Somehow, that and other contents of the OP suggested to me that the
construct using the redistributed mass of the moon was intended to be
one upon which structures to house people could be built.
In my mind, I guess I assumed that there was no intent to have bullet-
sized projectiles running loose all around with orbital velocities.
This would seem to render such a space unfit for habitation.

BTW, the Rings of Saturn are NOT stable. Inelastic collisions between
component particles of the Rings bleed off energy, perturbations due
to the celestial mechanics and friction from collisions with solar
wind and tenuous gases do the same. The orbits of the Rings are slowly
decaying. The same would happen to earth rings:
