You really don't understand. You need to be able to take more than a day off without getting evicted/loosing your car or eating oats most days. Go tell people that they don't need a home, their job and it's meager benefits like healthcare, and they should just be more stoic.

I just counted "a sufficiently stable life that it's still there when you return" as part of "safety" and "comfort". If traveling is a priority for you, you can live the life of a wandering monk, with the associated downsides.
