I have such a problem with the definition of the word "art" I'm not sure I can handle this, but my core answer is false. Money is required to sustain life. Time is required to earn money. There are people who are such talented artists that society is better if they spend all their time producting art, instead of working at McDs to feed themselves and making art in their spare times. So seperating art from money only works if you have artists who are independently wealthy, or if the art can be accomplished in spare time.

That said, deciding that you are an artist does not mean that society owes you a right to make a living solely creating whatever your artistic expression is. If you make art no one wants or enjoys, it may still be art (another discussion) but society is under no obligation to fund your pursuit of it full time.

The exchange of money for art can be seen as society valuing the contribution of the art. Society can be dumb, and wrong, but has the right to make decisions about what it will and will not support.
