I generally agree with your sentiment. I believe that techno-radical cost reduction is a more attainable and sustainable goal than universal basic income, which I fear will become inherently inflationary. However, although you didn't mention this, I don't think such a system could exist in a society of atomized individuals. Social bonds and communal effort are necessary to take care of everyone. Simply voting and hoping the market/government/taxes takes care of things is insufficient for achieving a fairer and more egalitarian societal structure for everybody.
