Mobile is the desperate last resort. Those that stay put get to keep all their stuff. That can be tough in tsunami or wildfire areas.
My ex-father-in-law (RIP - a great guy) survived the Nazi occupation of Poland by staying off the radar screen with a small family farm away from population centers. His city living half-brother was picked up for slave labor.
He was also able to provide supplemental food to his extended family during the communist years.
That’s the setup I’d choose if I had the resources.
I've given this a lot of thought and I TOTALLY AGREE.
I will add, it's not important just to be stationary, but to be stationary in the right community. I believe the ideal community is a small town (<10k population) with only a handful of roads leading in and out. I've been researching what I consider to be the best locations, and will be happy to discuss those with anyone via private message.
“Mobile is the desperate last resort.”
I think it depends. Depends on the threat and where its coming from.
