You can not be any more wrong about this. In space craft design, weight
is EVERYTHING.


For getting your payload (one time) up to space, after that weight is much
less of an issue. g

You're still wrong. There's no free lunch. Even things in
orbit will eventually fall back to earth unless you keep kicking
them back. The ISS uses thrusters for both keeping the orbit
from degrading and (in coordination with gyroscopes) to hold
the proper orientation. Objects in space still have MASS.
The amount of thruster fuel consumed depends on the mass.
