I think it's worth bearing in mind that Hayek lived before the information age, and that there are real limits to the validity of the idea that design isn't useful (and especially in economics/finance).

UBI may not be a good idea, but the reason being that it's likely not the best design (I would say Minsky had it largely correct [0]).
