yess! Why limit subsidizing to artists though?
Freeing anybody from the need to care for their survival would enable them to live in a more creative mindset.
And normalized creativity is a multiplicator for many things things our society needs (participation, openness,...)
This makes the term 'artist' in its current form ('person trying to capitalize aesthetics for survival, possibly out of passion') kinda meaningless, as creating is then about passion, not need.
