Explain why that is a “responsibility of a strong society” rather than simply a fool and his money are soon parted. I like having the option to throw my money in a wishing well if I were so inclined.

For real?

Because when a fool is parted from his money he and those who depend on him starve to death, and that, dear friend, is the part a strong society should be concerned about.

Universal basic income might cleanly solve that problem. Might, because the addict might spend the weekly income on the addiction instead of food and shelter.
