The social issues involved here are diverse and clearly do need to be addressed, but attempting to take the high moral ground does nothing to achieve that. People fall on hard times either through unfortunate circumstances, ill health, or because of ill-considered lifestyle choices, and as sorry as I am for them, realistically I wouldn't want to have to pick my way through rough sleepers whenever I entered or left my home - and I doubt many faced with that situation would either - regardless of what they say here. I would have no objection to these studs being installed outside my house if necessary.
