The point of basic income isn't to cover everything one could want out of life. It's to cover basic living expenses. Basic housing, basic food, a basic life. If basic income existed, then people would want more. That's not a strike against basic income, but just the opposite: it's a reason why basic income is more likely to work than, say, socialism. People who want more out of life can have it, whereas people who are satisfied with little can have little. The cost of specialized labor will never disappear.

I'd rather not subject my personal belief system to public analysis, because the average public opinion on beliefs is an average belief system, and the average belief system in any era has almost always been crazy.
