This sounds like unnecessary complexity as well as something that could cause problems. I don&#x27;t think there is a need to restrict people to necessities when paying them a minimal income, they&#x27;ll do that themselves.<p>It is overly judgemental of what people living on a basic income are allowed to do, thus making living on only the basic income less viable. Your mother is dying and you need to fly to a different city to visit her? Nope sorry, long distance transit is a nicety. You want to take some time to switch careers? Sorry, books are a nicety. Have back trouble? Sorry a fancy chair is a nicety. You may say that those things could be necessities but a huge fraction of goods typically a &#x27;nicety&#x27; can be a &#x27;necessity&#x27; in the right circumstances. Better not to tie people&#x27;s hands.<p>I think this adds a lot of complexity, cost and bureaucracy for a net loss in how effective the basic income is.
