Just to answer the question in this specific case: yes, a working class guy can decide he wants to pursue art (in quite a broad range of forms), and he can apply for the basic income once he can show that he is working as an artist. The artists who ultimately receive the payment will be chosen randomly once they meet the criteria to apply in the first place (which, again, is simply that you are working as an artist—exhibiting, publishing, performing, whatever "work" might mean in your case). There is a fixed number of people who can receive it in each round (I think it's 2500 people, cycling every three years), and those people are picked by lottery; if you receive it in one round, you cannot apply for the next. This, and in fact no arts funding in Ireland, has anything to do with certain universities or art degrees. This scheme is far from perfect, but these vaguely leading questions (so common to all commentary on public funding for the arts) are clearly irrelevant.

As for the second question ("would Daniel James work have been as good if he wasn't working in an ironworks"), well, life and art really are too varied to draw the kind of conclusions the following comment implies.
