I would add to the article's list of reasons why minimum income is a good idea the very Roman purpose behind public aid: to prevent civil unrest.
And I'd second sama's mention of controlling cost of living. In addition to universally obvious importance of it, with minimum income there is the added possibility that prices for low end necessities could rise commensurate with the size of the minimum guaranteed income.
A third point I'd raise is to ask about medical costs which, unlike Finland or Canada, if this test is carried out in the US, would be a very significant factor. If the minimum income needs to cover this too then healthy, and generally the young may tend to have vastly more disposable income while an unexpected illness for anyone could far exceed anything the minimum income could hope to cover.
