You are assuming that there is enough infrastructure to provide a
border router. In this case I would buy a border router and connect
a single host to the inside port and the outside port to my uplink.
It's a waste of hardware, and provides no value in the
configuration. Because again, why should the host trust an IP
address which should never reach it?
