Then you have to deal with port collisions when some other software wants to use that port. And keeping a port open without any authentication is terrible for security, even if it only binds on localhost, so you have to find some secure way to share a key between the client and server.
Personally I wish we could just use UNIX sockets for "localhost-only TCP", but software support is just not there.
