Right. What you describe is a post-scarcity society. One in which the citizens essentially do nothing but exist in a world where everything is automated.

This is something that may one day be achievable through innovation, but attempting to legislate it into reality before then is ... well ... in politics they might call that the tail wagging the dog.

A post-scarcity society is inevitable if technology continues to advance, but UBI still sounds like forcing the issue before it is feasible. You want this future ... I want this future, too.
