Great ideas! Now when I go be a nomad, or go to live with friends, should I bring the wife and kids (and dogs) along too, for the laugh? I have about as much scope of move 1 hour down the road as I do to move to the Moon!
I don't think the list is meant to be a "you must do these things" list, it's more to say "yes, you can absolutely do this if you want to, there is no cosmic force that stops you if _this is what you want_. I get your comment was incredulous towards an idea which isn't want you would want for yourself and your family, but my understanding is that the author's intent was to share their own realization that just because the things on their list are sometimes considered unusual or not normal doesn't mean you're forbidden from doing them. I think the author's point is more "you should not needlessly exclude valid options" as you're finding out what you really want to do in any element of life.
So your statement of incredulity is understood, sure -- you wouldn't want this right for yourself and your family at this time. The point is that if it is something you and your family wanted to do and could do, then the fact that it's not common for families to be nomadic shouldn't be a reason why you don't do it.
I mean, I'm sure that if you'd really want to, you'd come with a creative solution that would be beneficial for everyone. People with skin in the game that feel a particular need so strong as if they need to breathe oxygen, they usually have a shot at making stuff like this work, others don't.
That's my experience at least. I've heard quite a few times that what I'd do is impossible. Then they saw me do it and then I heard "oh but if you do it that way, then yea, with a lot of effort is is possible."
It's a mindset thingy, and the mindset that I see written in your comment feels like "I can't realistically." I get that, but IMO it's not the most helpful mindset if you want to do things that are slightly (or completely) off the beaten path. Martin Seligman's book helped in this aspect (Learned Optimism: How to Change Your Mind and Your Life).
