The parent comment said "spend it all on an addiction or just make a bad investment". What do we do with the person that gets e.g. their 1000€, spends it on a night with champagne and then has nothing to eat or pay their rent? Too outlandish for you? How about if they spend it on a new TV instead of rent, a new smartphone or a couch?
There's a reason why some people get into debt because of consumption: they don't plan reasonably. What do we do? Do we not pay them UBI but give them pocket money and keep the programs in place to cover their rent etc because they can't be trusted to take care of that with money we give them? Do we just ignore their fate and watch them go hungry and eventually homeless? Do we keep the programs in place, give them UBI and then pay their rent when they spend the UBI but didn't include the rent?
