I disagree with the "doing nothing is good for the soul" one only for UBI experiments bearing out that even in a vacuum of satisfied needs people will still tend to make project work for themselves just to have something to do to not be bored.
Being able to relax at one's own discretion and necessity is healthy, but having something to say you do for yourself is evidently somewhere in that hierarchy of needs.
It is definitely healthy to be able to take time and actually do nothing though. Like having a cup of tea in the morning, and just sitting and waking up slowly. That's good for the soul
I have this theory that much of the world's conflict comes from miscommunication or misinterpreting original intent and this is a great example. Who's right? idk! But both sides are adamant they are.
