Stone Age settlement found under the sea in Denmark

> As today’s world faces rising sea levels driven by climate change, the researchers hope to shed light on how Stone Age societies adapted to shifting coastlines more than eight millennia ago.

Unfortunately I don't expect there is any particularly reusable solution to be uncovered. Ancient peoples facing rising tides almost certainly just walked a bit inland and built new huts there. They probably thought nothing of it. They were a far more physically mobile culture, without great dependence on immense, immovable infrastructure - nor on rigid land ownership rules.

Our culture's migration will be entirely different.

Rigid land ownership seems to be the source of a great deal of our troubles.

Now try non-rigid land ownership, where land and buildings can be expropriated in the name of nebulous greater good.

Been there, done that, it is worse than the alternative. People will stop cultivating anything, because why bother if a random officer can just take things from you at will.

Western regulations about land appropriation are strict for a reason, and they always require just compensation for a reason. That is the only way to prevent powerful people from just grabbing what they want, cloaking the thieving act in word bubbles about common prosperity.

I don't think it's fair to pretend the only options humans have are the extremes of private and state ownership. Greed and the weight of capitalism under rail expansion in the US completely obliterated at least 15-20k years worth of Indigenous "non-rigid land ownership", being the apex system of human power consolidation and all that.

Native American nations and tribes didn't "own" land in the way that European colonizers did, under a doctrine of private property, written deeds and legal systems. Even under tribal territories, access was fluid.

America and its land was held communally by tribes and was generally understood in terms of use rights. If your nation, family or tribe cultivated a field, you had rights to that field as long as you actively used it. And stewardship of the land was seen as something to care for, not a commodity.

And this was the way things were in America up until a few hundred years ago.
