You should read "Utopia for Realists". It gave countless examples in history where providing unconditional basic income works. Even as we speak, other countries in the past decades did trial on universal basic income and it worked. In one experiment, twelve homeless folks were given regular unconditional cash grants. Except for one, all cleaned themselves up and are renting an accommodation.

UBI works unquestionably. But how has it not been implemented yet? Aside from the "fuck you, got mine" attitude, as well as I hypothesise that in evolutionary psychology, because energy upkeep is high-demanding, it makes us think not contributing to a group in any capacity is being a dead weight, UBI is still not implemented because many say that property owners will abuse unconditional income by raising rent prices. Instead, many propose universal basic utilities, meaning everyone would get free housing and utilities, but still working to get their own food presumably.

But I do not know about the arguments on UBI and basic utilities because of the emerging and inevitable usurpation of humans by AI on the labour market. The current thinking on both UBI and basic utilities is making presumptions of operating under the current free market framework-- that everyone will still be working in some ways and contributing to society. Sooner or later, with the coming of AI, the current mindset about working as a default behaviour is becoming obsolete and being relegated, in my opinion, as a relic of evolutionary psychology.
