I wouldn't advocate the use of antiquated technologies to accomplish this. The idea here is currency-free communities who live just as efficiently as currency-rich communities. But you have to start somewhere. What are the tools you need to build in order to build the tools to build the tools that build the tools, etc. that you need in order to live as efficiently as we do today.

Sure it wouldn't be as easy for many, but imagine a line below which folks who live in a currency-dependent economy would actually be better off to leave it. As more and more people fall below that line, the alternative way of life becomes more viable to sustain itself.

The thing that the wealthiest folks don't seem to realize is it's in their best interest to ensure the little guy has money. When a significant percentage of the population loses incentive to accumulate wealth you lose value on a global scale.
