That "going home" to bricks and mortar will become a chore once one transforms your build into what becomes very comfortable.True, but every time you go to a new place it's a new experience, and you guys do eventually head home, even if just to restock and handle various life things. Living in a van full time with no place to go to, that probably gets old.
If you have ties to your B&M, relatives local who would benefit from your presence, that is a whole different story. Many different reasons, economic, family, etc.
Of course if you are fulltime on a limited income and can't travel because you are afraid of costs or getting covid, well, you need to adjust your state of mind AND do something to better your situation.
Diane and I lived and travelled throughout Central America for ten years. We built a home in Costa Rica to use as a base, sense of community, and that seemed the "new/old normal". Believe me, after cruising the US for a couple of years, we debunked the that old/normal state of mind. Like a boat, the best day of our life was the day we sold our CR property. Less obligation stress and finally freedom. We love CR and we can couch surf with the hundreds of friends we have made if we get homesick.
Existence, happiness and security is nothing more than a state of mind. You control that state of mind.
