argparse is just a tool for dealing with command-line *flags*, which are
common in command-line tools.  argparse interprets the command line as a
bunch of flags because that's what it's designed to do.  I find it
baffling that you expect some other behavior from argparse.

You don't need or want argparse in this situation. sys.argv has
everything you need in it. Use it directly!
