There is a guiding Utopian goal of modern economics: a utopia for the rich.
Unfortunately, a utopia for the rich involves slave labor, inequal enforcement of law, and large class differences and privileges.
A true Utopia is very democratic to the point of communism. Then came Communism, and the rich and powerful said "no thanks" and then usurped the civilization struggle of the cold war to undermine all socialist movements from the New Deal/Great Depression and value the rich and powerful above all.
Anyway, it's funny because the point of UBI to me is pretty obvious in our highly hockey-sticked wealth distribution.
Fundamentally: don't let people starve or go homeless, let them get reasonable health care, and that will trigger enough GDP goods/services exchange that the economic impact shouldn't actually be that negative.
Although globally this is just sheltering Americans from the economic class they are all headed toward, the same economic class that the Chinese factory worker is: disposable worker bee, and constructing an intermediate global class for first world citizens, but it's kind of been like that informally for decades now.
The difference is the free trade economists can't keep saying with a straight face that free trade will be good for American workers as their jobs disappear, they retreat to opioids and suicide, and the rest of the global workforce get a couple cents an hour raise.
Well, at least the rest of the world has universal healthcare.
