It's the reality of many families all over the world, so, yes, you can if you want to I think is what the article is suggesting.
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.
