Every space station ever launched has had thrusters on it.

Take ISS as an example. ISS is 400 mT and Zarya/Zvezda provide about 10 mT of hypergolic propellant capacity. Less than 100 m/s of orbital maneuvering there. Not enough to go anywhere and meant for station keeping.

Which, if you read Robotbeat's post, is exactly his point when it comes to this station. Ya need a tug to move it anywhere.
