Nice alternative way of living. However, not for me. I lived in a tiny room in the house of my parents, I lived in tiny rooms in students‘ dorms, in tiny apartments and being rather tall, I am glad to find seats and tables and work places being somewhat comfortable for my size. I went camping when my children were little and still use tents when going to to festivals.
But now after so many years living like Snowhite in the world of dwarves I am so happy to live in a big house.
With smart organization and tools and quite some experience cleaning isn‘t that time consuming. For me, freedom means my garden all around, changing from room to room whenever I like. It‘s so wonderful after living in little boxes.
When I travel I live in simple rooms and that‘s no problem as I know I feel like in heaven when I am back.
I am glad that I found my individual way.
I agree with you about the benefit of minimalism, however. I live as simple as possible. It‘s so peaceful. I just need more space... and allow myself to enjoy it... :)
