However, one can argue that the expendable SSTO approach puts almost an
order of magnitude more mass into orbit, which is what I am suggesting.

Has anyone ever put anything into orbit with a single stage? I know
we've managed SSTS, Single Stage To Space, but I don't think we've
managed SSTO.

I assume there's an implied "earth" before orbit there, since all the
lunar landing LMs' ascent stages were SSTO, albeit lunar.
