Well, actually, I believe the big sell for the Shuttle program was an
obsession with reusability. Now, reusability in itself is no vice, but
I believe it was take too far so that it overrides many other factors,
such as overall costs. (Those costs appear to be much higher,
especially now with the loss of a second orbiter long before its
designed lifetime of 100 missions.)
Notably, most space launches, even those done by NASA use old throw away
rockets, such as the Titan II. It would be nice to do a study to see
which has been more efficient over the years -- the Shuttle or throw
away boosters? (Since the late 1970s, NASA put all its "manned" eggs in
the Shuttle basket. This would make the comparison harder.)

The idea has been suggested for many years of doing just that. NASA
could get into the business of selling orbiting main fuel tanks too to
make up for budget shortfalls. Right now, they burn up on reentry -- a
waste, IMHO.
