I used to be employed in a community where the vast majority of people collected welfare and did not work.
Except that most of the people who did not work actually did work. They would hunt for food, chop fire wood, haul their garbage to the dump, cook their own food, raise their own children, and do the many other things that are necessary to live.
I'm not saying that they type of person you describe does not exist. They do. Some of them lived in the very community I described. I am saying that because we tend to have a very specific, and peculiar, idea of what work means. We almost universally mean working for another. It doesn't much matter whether we are an employer or an employee, the product of that work is typically meant for someone outside of our family, social circles, and community. At the same time we dismiss any form of labour that isn't based upon some sort of transaction, the type of labour that is central to the health of both families and communities. Our culture has these notions so entrenched that the lack of a "proper job" does destroy people, psychologically. Not only is one's sense of value lost, but the value of other types of relationships is greatly diminished.
I don't really see worker rights or labour regulations as a complete solution since we are dealing with a problem that is stitched into the fabric of our society. Likewise, UBI is not a complete solution. If we were to dive into UBI today, which is about providing for people's basic needs from our surpluses (it is not about providing easy wealth), some people would be destroyed because we have never put much thought into what it means to live without there being some sort of transaction. We have never put much thought into what a non-authoritarian workplace would look like. We have never put much thought into what we need and our relationship with society as a whole.
The question that I have trouble answering is how can we build the foundation of a society where we aren't simply asking whether we work to live or live to work? A society where people's needs are met without coercion. A world where people want to contribute to a more egalitarian society.
