I definitely agree with Reuben here -- I just ran into this issue while creating a "production quality" tool, and the help message produced by argparse with nargs='*' confused me too. It's pretty clear that this is a simple bug in argparse's production of that usage message: it says ARGUMENT is required, but it isn't. However, the workaround of specifying an (unused) default is a reasonable workaround in the meantime -- thanks Paul.
