At the end, the article says that these design features don't solve the problem of homelessness. Clearly they don't, but several of these would be used in front of private property, not city property. How wrong is it for, say, a store owner to use these features to keep homeless people away from their storefronts? I can understand store owners being concerned about a loss of customers if there are homeless people nearby.
