presently on our planet : - ) Even between systems the use of optimum
trajectories and gravity assist will reduce the use of reaction mass.
The problem will come when we wish to travel faster to our
destination.

be wise to use up all the mass of Ceres for instance; I don't think
we should tamper with the larger bodies in the Solar System beyond a
certain limit. For our Moon I would say we should not tamper with its
mass beyond 5% (preferably 1%).
