For example, because half of other people's work is bullshit. Or because a third of other people's work output is used to take them from home to work. Or because the amount on the paycheck is totally unrelated to the value a worker produces. Or because a quarter of other people's work is not about creating value, but about destroying it and driving all of us always faster towards a catastrophe.
In short, because most of world organised around work is nonsense. So getting a bit of money to live poorly without work is not any more nonsensical. That's a way to see it.
