the point would be to tour, like in olden days, while being able to repair on the side of the road. air cooled is simple and fewer parts to fail. air cooled bikes will run as long as water cooled will, longer without the first breakdown, in most cases. touring once meant you could keep riding a motorcycle every day while doing your own maintenance. living in thwe country, not a trip to see the country. then comes the "image" and the weekend trippers who ride to the dealerships to get their run pins and a new patch for their vest. ohh, and more farkles!
Gee, you make a compelling case for air-cooled! And you didn't even the best part: Fried shins and nuts!
