Community is not the answer.
There is a lot of nonsense talked about community.
Transition Towns has, for years, demonized the go-it-alone attitude of “preppers” and “survivalists” who expect to look to their own resources before those of their neighbours in a time of crisis, and it’s precisely and exactly wrong. A group of people who can all more-or-less stand on their own feet are stronger together than alone, but a group in which the average is less-than-survival together will simply tend to drag each-other down. There are simply no “economies of scale” in survival groups.
This is not to say that, for example, tribes are not incredibly resilient. But, like modern Mormons, there are intense social pressures on people to carry their weight - to be prepared, to be resilient, to be skilled, to add something of value to the tribal collective in exchange for their membership of it, to be an asset to your neighbours, not a burden.
When drowning the weak children became unacceptable to us, we made a State. I’m (of course) bending the causality here, but I’m also making a point - tribal societies often practiced euthenasia for the old, we are told - Eskimos who’d go off on a final hunting trip which consisted of sitting on an ice flow and drifting out to open sea, or deformed children left out in the snow. This stuff is no joke, and while I’m not an expert in the history (I’m aware these reports may have been biased by Colonial historians) we have to beware our own idealization of a prior state. We remember the benefits, but do not remember the costs.
In this context, the most vulernable need a State to protect them. A community cannot carry somebody who needs, say, kindey dialasis. A State can carry people with those kinds of medical costs, and so can the Market given a healthy health insurance system, but a community does not have the resources to amortize the costs of the weak.
There is a very real case to be made for the most vulnerable people in Greece to head for countries with a strong Welfare State and good free public health case. The safety net is necessary, and it’s still there in some places. Why not use one’s freedom as a European to take advantage of it?
On the second point, on scale… I think I’ve answered that to a degree, too. We need scale to amortize risks. Whether Europe is simply Too Big is a much, much harder question, but small unit societies cannot and do not carry their weakest members - they (often) drop them. If we’re to provide a really strong safety net, it may require quite a large political bloc to provide it, and I think that’s doubly true when we start talking about environmental protection. Large political blocs can make substantial dents in the global environmental situation by regulation. Smaller blocs know their actions don’t have much effect, so there’s a strong tendency to say “well, we’re only 1.3m people, what can we do?” and keep on burning the coal regardless.
I do believe we need massive local political control, but we also need to delegate upwards what we can’t do ourselves, and the burdens a small community cannot be expected to carry.
The Big State has Big Arms. The village does not.
