No. It's not absurd. In the vacuum of space, inertia will carry you the entire way. All you need is enough fuel to force your way through the Earth's thick atmosphere and gravity well and enough fuel to slow down a little on the way back while taking advantage of gravity.

The Space Shuttle doesn't "slow down" when it approaches the moon but it maintains it's speed while launching a tiny lander. Most of that intertia is then used for the trip home. This is why the Shuttle only needs huge fuel tanks that are dumped back to Earth almost the moment it reaches escape velocity.

The rockets don't burn any fuel for 99.99% of the trip because Star Wars is fiction.
