That's the "-nolisten tcp" option (see Xserver(1) or a recent BUGTRAQ
post from Fred Silva).

So you could do

startx -- -nolisten tcp

Interestingly, ssh X forwarding can still work under this, which means
that ssh can act as a client for a Unix domain socket when forwarding
a display, I think.  That's pretty amazing; I was sure ssh forwarding
was going to be TCP-only.
