I think UBI is definitely interesting, but it can't wholesale replace benefits. For example, a major illness like cancer now can wipe out your income, your savings, and a UBI quite easily. I think UBI might be better than a range of some lower end benefits - but the also exists a variation of needs where we should commit to helping people with, that is going to exceed almost any general UBI threshhold in many cases, and still needs to be covered as benefits.
