My suggestion from 2008 when Greece ran out of tear gas: https://groups.google.com/foru...
"Now, does this make any sense if you understand the possibilities of open manufacturing or an open society? In Greece you have a warm climate, access to oceans, lots of sun and wind, an educated populace with a 2000+ year history of democracy (on and off :-), no obvious external enemies declaring war, and so on. And they are so worried about their future ability to make and use things (which is how I translate "fears for Greece's economic future") that they are running out of tear gas? This all makes no *physical* sense. The place should be a paradise. Instead it is in "self-destruct mode" according to one editor. It must be *ideology*. Or, more correctly, ideology *embodied* in a certain type of productive infrastructure. ...
So, ironically, we have the worst of both systems. We could have a really centralized system run efficiently with a tiny fraction of the workforce now, with a lot less variety perhaps (that is, all the old Soviet Central Planning stuff would work now that we have the internet and great software and great designs and great computers if we accept some voluntary simplicity), but with everything very cheap (essentially, just given away) and 99% of the population doing whatever they wanted with their time. Or, we could have a freewheeling diverse gift economy of local open manufacturing where people just make whatever they want in an open way, with all sorts of useful and useless items. (Aspects of the two extremes may even converge, since what are the 99% of people going to do with the generic stuff but customize it? :-) Instead, we have a system in the middle that produces some variety at a huge expense of human effort taken away from family and civic duties, and it is a system now with so many questions about its uncertain future (including that anyone who is young will have a dignified place in the economic scheme of things) that an entire country has just run out of tear gas. This makes no sense (except of course, that some people do benefit from this, like tear gas manufacturers, school teachers who get paid to keep kids off the streets preparing them for non-existent jobs, people who are near the top of the economic hierarchy already and feel secure, etc.).
Anyway, this suggests one target of open manufacturing could be a community of size ranging from Iceland (about 300,000 people) to Greece (about 11,000,000 people). That's certainly an interesting size range. I would think 99% closure of those economies by mass should be easily doable. Computer chips, some medicines, and maybe some other specialized components might be the major imports after the system was set up. Note that while one may not expect Greece or Iceland to "self-replicate" any time soon, the ability do do so ensures it can be self-repairing.
Anyway, it kind of comes down to how much economic security is worth to a country compared to minimum effort. Given the massive youth unemployment in Greece, and the economic fears of depending on a global economy, it would seem like maximizing productive efficiency through participating in global production would not be at the top of their priority list now that they are out of tear gas. Unfortunately, they did not invest in this research ten years ago. So, this is only theoretical at this point. It might take a very expensive crash program to bring together thousands of researchers for a year to make headway in any time that might make a difference. Still, politically, that is an out for Greece. We could all move there, recruit all the educated youths off the streets, and spend a year figuring out how to make Greece work for everybody and be 99% self-sufficient by mass. :-) But, no need to move with the internet really. Maybe somebody on the list could coordinate moving the rioters off the streets and into internet cafes and start them programming and tagging designs with metadata? Anyway, with the right kind of enthusiasm, I bet someone who was in Greece could turn this whole thing around, recasting the Greek rioters as the potential people who would save the planet by implementing open manufacturing and cradle-to-cradle design."
