The vast majority of homeless are addicts and wouldn't move into free housing if provided, or mentally ill and should be cared for instead of dumped on the street - and also wouldn't remain in free housing even if provided - because they are mentally ill!

If you sincerely think homelessness is just a lack of housing I heartily encourage you to get out from behind your keyboard and go volunteer at a local homeless shelter. Ignorant people such as yourself are our real problem in making meaningful progress towards solving homelessness - luckily ignorance can be overcome if you choose to actually get involved. And it is rewarding when you do reach the occasional folks who are homeless but don't want to be and just need some help getting out. They may be the minority, but there are still many there and they are underserved. Those are the folks I focus on and what inspire me to remain involved.

Saying essentially the same thing twice does not an argument make. I'm sure if you re-read the article, you'll find that #2 doesn't even apply. And you haven't even bothered to refute the idea that it is a local government problem. Don't like it? Talk to the local zoning board. Otherwise, whining about the actions of individuals, assuming the law allows such actions, is going to do fuck-all to solve the problem.
