the problems this would solve is damn near incalculable. loitering would plummet, improved sanitation and hygiene would lead to fewer illnesses being transmitted. How many calls to police about homeless vagrancy, public urination/defecation, business owners complaints, panhandling wouldn't have to be made and responded to? Homelessness increases crime so after providing them housing society would see fewer assaults, murders, rapes, sex-trafficking, prostitution, drug abuse, theft, robberies and property damage.
