I don't need much. I honestly don't. I prefer quality and things that appeal to my interest over quantity. I've lived in dorms, hotels, and temp housing before. If it's just me, I can be comfortable and content in an average single bedroom apartment. I'd maybe prefer some outside storage and/or work space, but I don't need a three car garage. Although opinions vary on what constitutes enough, I'm good with having "just enough".
But, I don't think I'd enjoy this.
Having a small space of my own seems like it's pretty essential to my feeling secure and satisfied. Thinking about being constantly on the move, even with the ability to take all my possessions with me, gives me a sort of creeping anxiety and disquiet.
Part of it is that it feels invasive to me to live in other's homes. Oddly enough, I don't mind having someone in my space, but I'd be walking on eggshells if I did the same. I know that no housing is truly secure in the US economy, but this feels far too impermanent and far too at risk of going wrong.
You don't have to tell people you use Linux or talk to them about it. I know that because I use Zorin OS, which is a really modern feeling Linux distro with a slick user interface, that's perfect for people like you and I, who don't want to be bombarded with opinions on the "right" operating system and just want to use their computers in peace. You should totally switch!
