Well, JC - I ain't you and you ain't me. There are rational reasons 79tooth sprockets were put on the RT models and the European F3T & L models for touring. Even our renowned and respected Lamont of Lamonster Garage has indicated a desire for this and even a 7th gear. You might ask him, "why on earth for".
In my 70+ years, I have bombed all over America and Europe, riding one up with nary a concern about speed limits and roaring pipes. Now, I'd like to enjoy many leisure miles of 2-up riding with my 70 year-old wife.
As has been stated many times over on these forums - to each his own - I will be the last person to ridicule anyone else's ride, riding style or attitude.
And, by the way, at 71 years of age, I just completed a 3,000 mile unsupported bicycle ride from San Diego, California to St. Augustine, Florida. Now, go ahead and ask me, as many others have, "what the hell compelled you to do that?"
Blessings - I do enjoy your contribution to these forums.
