Only with current innefficient technologies. With more effecient engines and fuels (or even the sci-fi anti-gravity devices), you can eliminate the expense of getting materials into space.

Also, you can get materials from low gravity planets and asteroids too. Those require very little thrust to get the materials where you need them.
