That is a policy choice. Why do we need jobs if we're getting unlimited free stuff? The laws of physics aren't requiring us to - we are requiring us to.
The point is total economic dependence on _no one_, because we had basically had total economic dependence on the US and they fucked us into learning our lesson.
But other people are giving you everything you want for free. Why do you need to afford it? What does it even mean to question whether you can afford something you already get unlimited amounts of for free?
You said "everything you need". I need shelter, I need food and water, but I want powerful computing, fast internet, a phone with cell service, treats and snacks and etc. I want games to play with my friends, I want gifts to buy for my friends. I don't need those things, but they greatly contribute to my quality of life.

If I had unlimited money, my limiting resources would quickly become time and energy instead. So affording something would mean fitting it into my day/week/month/etc, and finding the energy for it. I have severe ADHD and executive dysfunction, so I don't always have the capacity for things I should be able to do.
