I have been following this for years, but the project does not progress very much (there are more machines, but the community has not grown). The village set would be both useful for civilization RE-construction and for civilization (First) construction in poor countries. In my first post in the EA Forum I tried to produce some interest either in this project or some susbtitute, because no other open source project could be more useful.
A discussion about this article including comments to your objection can be found here:
If fussion propulsion is possible, probably fussion would be available for energy production on Earth, and that would imply "energy too cheap to measure". The kind of economy under that regime would extremely different from ours. Under that conditions, for example, materials would be extremely easy to obtain from Earth (we could profitably mine minerals with far lower ore grades than we can now).
I think that if we ever reach the "energy too cheap to measure" economic regime, for example, extiction risk would be far lower than now. But we all know that Brazil is the country of the future, and allways will be, and that nuclear fussion will allways be 30 years in the future either... I hope I am wrong in both :-)
In a previous post I commented that before we deal with spaceships, we need a complete circular and almost self replicating human economy:

This is the hardest problem
It is obviously a critical consideration; beyond that, I would say that the best countries in the world are those with a long history of descentralization and a relatively less hierarchical urban structure: Switzerland, Germany and the United States. It makes life cheaper, allows people to live in bigger houses, the enviorment is better... Urbanization was a necessary evil and a necessary risk. Fortunately, less neccesary now.
Because cities are sitting ducks for nuclear weapons. We don't know if nuclear winter is real, but in case it were not, nuclear war would be survivable if human population and industry were spread.
There are obvious avenues for progress in our society: more income security, less working hours, ideally some degree of population de-concentration. Addionally, relatively poor countries still have a large room for economic improvement, and political and military risks are un un-acceptably large.
On the other hand, your criticism of the "rockets and flying cars" progress ideal looks spot on to me.
Perhaps you would find this post interesting too:
Kind Regards,
Arturo
