The gap that I see in this approach is everyone has a different definition of what is a nicety and what is a necessity.<p>To go with your tobacco example, I personally don&#x27;t believe that tobacco should be considered a necessity. (Though I have no problem with Nicorette &#x2F; nicotine gum being in that category, which could be used by someone unable to buy cigarettes to satisfy their craving.) Someone else may have a different definition of a necessity vs nicety altogether.<p>It&#x27;s much simpler IMO to just give people ordinary currency, and let them decide how to spend it best.
