I'll play the Devil's advocate. I might as well get on his good side.
Were leper colonies that bad an idea? Remember that at the time they were in place, there was no treatment for leprosy. Rather than risk widespread infection that could cripple or kill countless millions, governments of the time chose to quarantine people. Which is of greater importance, the relative freedom of an individual or the health of a population? Even today, the accepted practice with a new or untreatable disease is first to isolate the patient. This isn't just in the third world, but in nearly civilized countries like Canada (Toronto, SARS).
Back to the homeless. What to do about the unsalvagable ones? They do impact the quality of life and the economic climate of the places they inhabit and the people who live, work, or visit there. Exporting them to The Town Next Door may solve the problem for one place, but just creates a problem fo rthe next. Is an island a bad place for them?
