And it's also easy for the threat perimiter of that network to be
breached, often accidentally, by someone who has a machine to attach
to that network that has previously been attached to the public
network, or who dials up to a corporate network that is less well
secured, or so on. It's easy for the fact that the privacy of the
network is crucial to be forgotten over the years, as staff changes
and collective knowledge decays. The security of such a setup is
terribly fragile.

I won't say you can't do that; I'm happy to supply rope. But I will
say that you shouldn't, even if you think it's private and secure.
