You have a very balanced take, it's refreshing.
Poverty and drug addiction is a very difficult problem I believe can be tackled by UBI and safe injection centres together.
I have the same gripes about the Montreal Metro, I think it's unsafe outside of commute hours because of the drug users and homeless people who take shelter within. It's not their fault, it's a societal problem, but the end result nonetheless is that people get assaulted frequently on the metro.
Being poor is expensive, both for the individual and for society, and studies show that if you give someone $200, they'll spend it on food and drugs. If you house someone, they'll feel like they have no autonomy and go back to the streets. If you give them $25k a year with no strings attached, most will try to find housing they like, buy food they like and solve their addiction and mental health issues, and go on to live fulfilling lives.
And, best of all, if done and funded correctly, employers get to save $25k a year on employee paychecks as it'll be presumably garnered off of corporate taxes for all of society to enjoy. Unfortunately, companies are "people" and would protest against this as it'll end up being slightly more expensive in the short term.
Pushing poor people away just makes them someone else's problem.
