In other words, you have a versioning system that you can't use offline,
except for local diffs.

The big deal is a slightly different point. Making commit 'offline'
not only allows me to make commits while in the middle of nowhere
(and here in germany this easily includes trains).
It also allows me to make commits for a repo that I don't have
commit privileges for - I can commit my work in a meaningful way,
and later convince one of the official committers to pull these.
This also means that I can't maintain a patched version of
svn (or anything in an svn repo) without having commit
privilege to the source repo, or having to do the
vendor branch dance (with in itself is unnecessarily
annoying in svn).

It also makes a difference in speed - git log usually outputs data
faster than anybody can open an SSL connection in edge land.

You know that that is a straw man. There is no in-svn way to
reconcile that with another repo, and also I don't want to
start on an empty repo, but, say, on the current svn trunk.

That is also orthogonal. Being offline does not mean that other people
work in the same repo, let alone area of a product. Also, the alternative,
namely working on trunk and do frequent updates, is worse in comparison,
because then you end up in conflicts in you sandbox, and have no way
of backing out and trying again later.

Neither can non-distributed systems. The question is how long
you let work diverge, not where you do it.

Please. git managed to be faster in providing actually working
(i.e. tracked) merges than subversion, and then there was
the --reintegrate debacle that took another five years to
"Totally trivial. Famous last words."
