Why haven't you moved back? Genuinely curious.
Believe me, I agree with the idea of shedding useless stuff before a move. Which we have. But you tend to accumulate needed stuff with a family in tow. Also, keep in mind that the amount of money involved isn't just for moving physical items.
There's distance as well. I've moved across the entirety of the United States twice, mostly for jobs. Although it was a bit of adventurous thinking because we liked the idea of such a huge change.
I regret nothing.
That does change things a bit.
Like I said, often there are some good reasons sometimes many good reasons. But as a stereotype, in the US people will have lots of material possessions, most of which are crap.
I know the comfort of having your own things that have been with you throughout the years, and everything is exactly how you're used to them. I do miss the feeling, and will eventually settle down somewhere, or at least settle down my "things" somewhere.
I still couldn't resist pointing out that being geographically mobile is a viable option, even if it does require some effort, planning and certain trade-offs.
And it isn't totally binary, it's a scale from "living out of one luggage-sized suitcase" six flags -style, through being able to pack up and leave on a week's notice, to having planned a lifestyle around moving every couple of years, to having deep roots etc..
