From what I have read about UBI, the principle motivation is not so much to provide workers with a guaranteed minimum income as to enable people to choose not to become part of the conventional workforce. The effect of this would be to remove creative pursuits from the constraints of the market. The question I was trying to address was this: are we to value creativity and self fulfillment above the production of basic needs — food, clothing and shelter? We already value gadgets, entertainment and sports above such essential tasks; that is the way the market works. If we are to regard any human activity as being too important to have to rely on the market, then, surely, those tasks the performance of which is essential to life itself ought to be the ones.
