Conversion is the method. Since none (due to a bug, in fact a little, but it is probably not significant) is being created, as SBD is destroyed by conversions its supply declines and eventually it will get to the point it is repegged at $1.
You are correct that inflation doesn't assure anything. It might result in an increased, decreased, or unchanged total value, depending on market conditions.
Oh, I totally forget to that option, although a few days ago I even converted some SBDs. Thank you for your time and shared knowledge. :)
