One particular inconsistency in the article is that it intersperses mentions of a sizeable mentally ill homeless population with an expectation and recommendation that they can be supported or housed in a manner that requires these people to accept responsibility for themselves and keep to a "single standard of behavior for all" - which is not really compatible with many of the involved mental illnesses.

The author does mention relevant aspects of multiple different subgroups, but still suggests various universal "solutions" that might work for one group but obviously can't work for another.
