The problem with that viewpoint is that you assume that the only reason - or, even, the most important reason - that people work is to make money.

But our understanding of human behavior tells us that other factors like status games, feelings of personal achievement or 'having a purpose in life', and so on are equally as important, if not more important, than the money-making aspect of work. Further, something that someone considers 'work' could be considered enjoyment by someone else.

Believe it or not, many people farm or tend gardens or animals simply because they enjoy doing so. They may even give away their produce for free. I currently have several trees and I pick and give away their fruit for free. I used to have chickens and I gave away their eggs for free. Both of these I did because I enjoyed doing them, and the hard aspects of the work averaged out. Of course I am not saying that a system based on everyone doing this would be sustainable. It wouldn't. It would probably lead to food shortages. However, it offers a counterpoint to the idea that humans will always choose meditation or video games or somesuch over 'mucking in the dirt' if given the choice.

I think Xyrik's scenario is too radical but a system of universal basic income where everyone gets a minimal amount of money sufficient for survival is quite tenable and sustainable. In such a system, you don't have to work to survive, but working produces a better, more satisfactory form of survival. Experience shows that systems like these do not run into problems of food shortages (in fact quite the contrary).
