It’s nonsense on every level. The fact that a system can drive down costs doesn’t mean it can drive them down to zero. And that’s not what we’re seeing anywhere. It also says nothing about the cost of resources for labor to convert to goods.
Moreover, all societies engage in distribution (I reject the notion of “re”-distribution because that falsely implies that any initial distribution was somehow natural). although no society has ever gotten UBI to work on any scale.
