I like this list, but "what is not needed should not be made" basically ends all processes of discovery and creativity.
Also who decides what is needed? Sure, ideally we live in an equitable and inclusive society and everyone's need are respected, but we don't yet, and many people today see, for example, things disabled people need to exist, as completely unnecessary, extravagant, and even harmful, and would happily stop producing at our expense.
I get what they're trying to say, we absolutely make enormous amount of shit no one needs to feed an endless cycle of overconsumption created because line must go up, but they're focusing on the wrong part. It isn't production that is the problem, humans have always wanted to make things, it is the "for profit" component that leads to all the problems, because you're not just selling (E: or ideally simply making) to meet a need, you're creating needs that don't exist so you can sell, and always prioritise profit over anything else (sustainability, working conditions, quality, and so on).
