If you want justification, leave our office, drive out to the local
airport (or truck stop), and look at the sort of routine maintenance 
that real transportation systems require.  To turn an airliner around
between flights, they unload the passengers, refuel, vacuum the interior, 
and run through the preflight checklist.  Unless something unexpected
crops up, that's all they do.  Any additional maintenance, even something
as a new coat of paint, would more than double the operating cost.  More
complex work, like stacking and mating stages, would probably increase it
by a factor of 10.
