This is an interesting definition of "minimal computing". However, I don't really agree with a lot of the points.

Minimalism is about caring only about what is important and leaving the rest out of the way.
The authors seem to have chosen what they themselves think is important for their lifestyle, not what can be applied to everyone and anyone. For example, we can know what they care about: "Mobility", "Negotiation/flexibility", "Justice", "Access", "Ephemerality". That will contradict with someone who wants a minimal system that is stable, long term, in a fixed place. Or it's going to clash with people who want to rely on thin-clients like chromebooks and store their data in the cloud, accessible everywhere, and without learning curve.

tl;dr For each their own.
