Edward Griffin has also talked about the power of community or as he calls it, the power of numbers.
"The power of numbers. Cooperation has a squaring effect. Two people working separately in the same community have the force of two; but, working together, they have the force of four. Three working together have the effect of nine working separately. Four have the effect of sixteen, and so on. Just imagine the influence that is possible from the cooperation of fifty or a hundred people all dedicated to the same goal."
...This is the goal of the FreeStateProject (freestateproject.org) so if you are looking for a way to be effective, this is one good way to do it. Imagine what could happen with 20,000 people working together in a state with representatives for approx. every 3,000 people and 5-seat executive council unusually similar to Switzerland's form of government.
