Even if universal basic income was a pipe dream (which I vehemently disagree with, and again point to the examples above as evidence that not needing to work does not lead to societal collapse), I don't see why enabling everyone the freedom to work on whatever they want should not be a goal.
If it were up to me, taxes would be funded via land value tax (commonly referred to as the fairest and most efficient tax since there's no deadweight loss), and the proceeds would be distributed uniformly to the population as a citizen's dividend.
