Well, the "Malibu surfer" is a recurrent theme. E.g. https://link.springer.com/chapter/10.1007%2F978-3-030-37908-... or https://www.jstor.org/stable/2265291. Van Parijs (author of the last text) is very well known in the field of UBI (some sources even list him as the founder of the idea). The haiku theme often arises in discussions, but I cannot find a source. Anyway, is the same idea: being paid for doing whatever you want or nothing at all.

What you talk about is not UBI, but other schema of basic income conditioned (thus not fulfilling the U).
