When you join the swarm for a given piece of content and you can see the
others in the swarm. This is fundamental for P2P file transfer and
certain other purposes. There are systems that cloak the swarm's IPs,
used almost exclusively by pirates. You probably knew that.

You state "There is a large amount of content that people view which is

It's not that the content is "embarrassing but not illegal."
Rather, it's that it's being expeditiously and efficiently distributed,
thanks to ALTO, without the content owner's permission (which I assume
is either the girls or the sheep).
It is not difficult to look out for their interests. Why wouldn't we?
b) Not to sidetrack my central point (above), but it seems to me it's a
bit of a hollow exercise to call for privacy while noting "Someone
within the network can always see who else is viewing that file if they
can get the hashkey for that file..."
I'm not a privacy expert. Am I missing something?

There is a large amount of content that people view which is
embarrasing but not illegal.
EG, suppose you use a P2P system to view a video about, say, girls who
are unnaturally attracted to sheep. Filmed where it was legal, and
you're watching it in San Francisco (where community standards are
uhh, interesting...)
Should I or someone else be able to query a localization server for
"All those into NSFW ovine videos?" Obviously not.
The problem is, however, you CAN'T actually have privacy preserving to
the degree some would want.
Someone within the network can always see who else is viewing that
file if they can get the hashkey for that file, in pretty much any P2P
system at all, and the localization server may help in this process
but isn't essential for this process.
If the model is "anyone can add a hashkey" to the system, you will
have pirated material, and if the keys are identified by the content
owner, the DMCA or similar should be reasonable to take them down
(assuming you want to play whak-a-mole on localization servers which,
if removed, would not affect people's ability to get the pirated
content).
But you also have significant noninfringing uses which need the
"anyone can add a key" model.
