Great story and great life really when you think about it.

The freedom that you had and have, the simple, but seriously adventurous life that you have lived so far- and taught your kid to be resilient, adventurous, self reliant, frugal, flexible- all the important thing that most kids/young adults wouldn't have a clue about these days....and that's what most oldies told themselves just as their about to get married in the late teens and early twenties...'its ok, I'll travel Australia/the world when the kids grow up and leave home and so some of them do, some of them try, but many never do and die first- like mine did and so I learnt from their mistakes, left home at 17 and spent years traveling, going from job to job, backpackers and so on and living in Melbourne since 2005 is bar far the longest I have ever lived in my 53 years and heading back up to the Daintree next Monday to do some recon in Cairns as I'm thinking about moving back up there again when my lease runs out in Feb, but then I'm also wanting to go back to Thailand to just do nothing but volunteer in animals sanctuaries again, and I am really dying to go OS to Europe for a while (never been for more than a couple of weeks) and I have to remember that I now have Mum's parrot, so I may or may not go anywhere OS...

So if you do ever enter in the home ownership bubble, you'll soon be missing that fresh air and freedom that you guys have now, so well done and be free.

Cross the pension bridge when you come to it.
Even if you have stuff all super and have to live off a meager pension, atleast you'll be used to living frugally and it won't hurt so much.

That's what I'm going to do..(no choice there either...lol...)
