Having family on Kauai, I know they miss the "Superferry" system, as they could have had a variety of choices in choosing how to travel "interisland" instead of paying for "Hawaiian Air's" monopoly prices.  

It's fine if you can't imagine or see, what the superferry offered in transportation options; it just means that you can't seem to see the "bigger picture" offered for businesses on the outer islands.  Profit comes in many different forms and in the case of the Superferry, there were other markets available to be tapped, but the Superferry business was never allowed to mature enough to the point where they could have branched out into different segments of the available inter-island market.

As to your fear of the "homeless" having access to a car, means nothing; as in order to get to an outer island, they would have had to pay for the car to be transported on the superferry and there were strictly followed rules and regulations on what could be transported.
