I think the reason youd want to rule this out is because of democracy and the unwillingness of workers to pay UBI to non-workers. I don’t see a situation where people would be comfortable where workers pay more taxes so people can choose not to work. There’s not enough billionaires (yet) to tax at 90% to cover this. I think a more reasonable approach to UBI is to reduce costs for staple goods to such a low rate that it doesn’t cost as much and the need to work is reduced without raising taxes or introducing a freeloader problem. This is positive outcome of AI and cheap energy (think Star Trek).
