For the arts, free studios & such are both en-masse support, and a wider part of the talent funnel (vs. basic incomes).

Biggest problem that I see with basic incomes is in selecting who gets those. The article notes they'll pick randomly from 8,000 applicants - but there's judgement and selection somewhere. Otherwise, the scheme would implode politically after giving money to folks whose "art" was offensive graffiti, or appreciating expensive whiskey, or whatever.
