How many people are capable of doing nothing thou, 9x% of people will still find something productive (either in the current commercial sence or more the art/craft sence) or find someother way to find satisfy their more personal needs/desires.
There is an anecdote of a Canadian town that tried (for ~1 year) this during the 80's and one of the people they focussed one, got a job as the janitor at the local high school and loved it so much, that by choice he was there post retirment age.
Because the very meaning of work would be "accomplishment" and/or "creativity". Without the pressure you mention. I know so well what it is to work for food and housing... And it's not correlate to the "sparkling" moments of my life. What is interesting with the Dutch experiment... is that it's an experiment! Less ideology and more data!
