I certainly didn't mean to suggest you're concocting it yourself, but until it exists it still is a situation we're imagining. It's hard to really imagine what that change will be sufficiently enough to start reworking the way we engage our economy and society. But I do think it's a bit difficult to swallow that we'll just suddenly not need jobs any more. More than likely what happens, if we followed your scenario, is that we'd have a large class of non-productive or largely consuming group of people and another class of people that were still working/servicing/producing. I have to imagine that divide would not endure as a pleasant one in which everyone enjoyed their role relative to the other. Specifically, the producers/servicers would pretty quickly resent the other class. So, not dissimilar to now in terms of class warfare but with a lot less people contributing to society. (Which, IMO, is a much more volatile powder keg)
