Interesting discussion indeed. Personally I think past some point of automatisation and concentration of production means, these means will need to be made a public resource in some way.

Ideally the owners of the factories/robot armies will have an upside to that deal, but I think once a huge proportion of the population cannot produce and the basic goods are completely delivered by a few private parties,the social balance would collapse and could lead to a revolution.

About employment, I think the notion of work would change, and we'get back to a concept of occupying people. Of course entertainment would be of super high value, but one could imagine that fields with very low return on time invested like research, social care, artisanal craft or art/monuments building would also raise in popularity, with some additional sense of urgency so people emotionaly engage with their 'work'.

In that system people still get value from their work, don't need to feel assisted under a 'basic income' banner. What they do just doesn't affect production of basic goods anymore.

Also religion and gambling and cruel games would be on the rise.
