I think of minimalism as an aesthetic or study in aesthetics that helps people live in gratitude for the things they do have. Minimalism has a core rooted in calm and pleasantness and I feel like if this ‘nomadic’ minimalism you’re describing fits into that then it could be a branch of minimalism. But the picture here is kind of depressing, haphazard, and I can’t imagine the person whose place that is would like to live that way for a long time. They did take a picture of it… I did that when I moved into my place but it was like ‘look how I’m living in squalor’.
