Earlier quoted context omitted.
Why is it a dumb decision?
It makes it, not just de facto, but de jure illegal to be poor. If someone can't afford a home, where are they meant to go? Just fuck off and die?
In the meantime, yeah this is terrible for anyone who is homeless. It could very well do a disservice describing eh ruling as making being poor illegal though. The ruling only covers homeless camps, there are still a ton of poor people who do still have a roof over their heads that aren't breaking the law by being poor.
