This may actually end up being an intrinsic part of the anarchy capitalyst system, anyway, simply because for security and insurance, it is cheaper to keep people fed and housed, than to prevent them from using weapons to steal such necessities. NY did a study a short while ago where they found out it cost the government about $600 a month in police and medical expenses to manage each homeless person, meaning it would be easier to just give them $600 worth of food and housing.
