This is a common misconception. Everyone can have a loopback device
(which allows you to do uninteresting things like telnet and ftp to
yourself). There are, however, other tcpip clients useful to everyone
even if you don't have a ethernet card. Talk/talkd for example.
Lpr/lpd is another. Even a proper implementation of who(1) should
use tcpip. X11 also uses tcpip. All without ever being connected to
anyone but yourself.
I hope a while down the road it will be the standard that tcpip is
compiled into the kernel (it doesn't even take up /that/ much space).
SLIP is also just down the road and everyone has a serial port.
