For those who won't ever be homeless, another thing to consider about UBI going to homeless addicts, is that the destitute no longer have to break into cars, steal from stores, or beg for change on the side of the street, just to survive.

It sucks when an addict steals the catalytic converter off your car. They cost a pretty penny to replace! (~$3000) Meanwhile the addict is getting $50, maybe a couple hundred dollars for it? UBI means surviving until the next UBI check (be it monthly or weekly or hourly) allows you to spend it on whatever they need. Be it drugs or alcohol or food.
