That would be interesting to explore. Still assumes a single system even if the power relationship is different. Is it too tin-foil-hat to say that centralised systems are both a reflection of and a preparation for a particular sort of digital society? Have felt this about the fact that schools are using biometrics for lunch payments and putting CCTV in toilets (https://www.theguardian.com/education/2017/nov/02/secondary-school-cctv-pupil-toilet-areas-summerhill-surveillance).

How could we design systems that show that other models are possible?
