I read it as all the human essentials are covered without work (sufficiently nutritious food, safe, clean, shelter with sufficient heating and water for basic needs, basic healthcare, basic internet, and a small extra for discretionary spending) with the assumption that most people will happily do
some work to upgrade their circumstances and get more fun and interesting food/entertainment/shelter.
If quitting your job doesn't put your life or your ability to get another job (because you're not capable of maintaining basic grooming, for example) at risk, then the "free market" model of employment can actually work, and people can opt out of jobs that treat them poorly or underpay them. At that point all the most essential/difficult/unpleasant jobs would actually have to pay the most, and cushier jobs with more reasonable hours could pay less, and people could do the amount of work it takes to get the amount of money they want. Think of how hard people work just to make a bit more money even when they're financially stable, just because they want a house or a cool car or a nice vacation. Why would that change if you didn't have to bleed yourself dry just to eat and sleep under a roof?
