What you describe is not a real choice that is being made. The unemployed in Ireland get unemployment benefits, so this isn't favouring one over the other. The Artist's UBI is not enough to live on (neither are most countries' unemployment benefits to be fair) but in general a salesperson or carpet installer when in employment will make a decent living, whereas artists don't. Society tends to under value the arts and overvalue commerce (and any free market arguments about this consistently fail to reflect reality), and this address some of the balance. They did an analysis (probably generously) and found that there would actually be an ROI for this UBI.
