It is all about the range of gears you want. I started touring 40 years ago with a double, moved to a triple, and now use a Rohloff (1x14). The Rohloff has a ultra low of about 16 inches and a high of around 85 inches. The low is lower than my double or triple and I don't care if I spin out with the high end only 85 since I am doing 20+ MPH by then. That is plenty fast the few times I have ridden along at that speed when not going downhill where I tend to gently pedal to keep the legs warm but not exert energy.
If you can pedal it, do what makes you happy and don't worry about what anyone says, if anything. Best, John
