I don't think comparisons to airplanes make much sense. While early airplanes may have only been accessible to the rich, at the same time the infrastructure required was very minimal. During the early stages of the aviation industry, not much more was needed than a field or lake. A minimally viable Hyperloop for the rich requires billions of dollars of infrastructure.

I agree that these comparisons are not direct analogies, which is why I said "I don't really have a direct analogy (possibly due to a lack of 'vision')".
