hey! so it turns out you can treat people with mental illness and addiction

What a novel idea, we've never tried that here in Finland. If we had heard about that we might've made a lot of programs to help them, house them. Surely that should've solved the issue completely. But alas, we never knew about such things.

but you know. those people are also unpleasant, so we should probably just make sure they can’t lay down anywhere. i mean, eff those assholes.

It would be unfair to them to make the public spaces, meant for all public, unpleasant for most people to cater to those who are hostile and threatening to others. Which is unfortunately the case with drunk and high addicts. You don't want to exclude homeless but you also can't allow them to exclude others with unacceptable behaviour. And public transit stations for example aren't meant for living or sleeping in, the benches are for temporary use, often for those with trouble standing. Someone using the bench to sleep on is taking it away from others. It's a tough situation. And housing is provided for everyone. Not everyone takes the offer, often for addiction and mental health issues. You can't exactly force them either.

I feel like you live in a much more magical world than I do, with much simpler solutions to what others consider big and difficult issues.
