@waweic Why would people work if they don't need to? After buying a house, I certainly wouldn't. And I need a house to live, so even that should be free according to OP. I would at most study or build something for myself, shun away from society.
They shouldn't and I agree with you. But UBI won't change that, while decentralization might favor the scales. How do you measure contribution to society? Is a doctor better than a teacher or a garbage collector?
