The problem with UBI is not the idea itself. It's the unintended consequences and edge cases. For example, it might be that UBI causes people to work MORE and die sooner at riskier jobs (like working oil fields). What is the net effect of that? Also, what if it doesn't do much more than inflate prices to the point that people still have to work just as much? Could it just reset the sort of "zero point" higher? What if people have an in-built need to work to have value in life? Would paying them not to work cause their life to lose its value and increase suicides or other negative behavior? Also, will people start having more kids to somehow get more UBI benefits? Large system changes mean serious consequences that go beyond the obvious. Anyone who has ever worked on a large software system surely have experienced this. I don't expect failure, but I do expect some seriously weird and unintended outcomes that are non-obvious.
