If you architect a system that accounts for networking changing states,
then it works for *everyone*.  If you depend on networking always being
there, then it only works for some subset of users that have one type of
installation.  Having one architecture and one codebase (that handles
both cases) generally means easier maintenance, feature addition, and
fewer bugs.

It's certainly  not a desktop view of things; many desktops stay on a
desk and are always connected to a network.  It's more a view that tries
to account for more use-cases than static networking scripts ever did.
But that doesn't mean it compromises the always-connected-never-moving
case either.
