I think it would be Keene.There is also agorist acres in Grafton
Hmm, you could even set up a logistic company that ferry goods between Keene and Grafton. I think somebody in both Keene and Grafton must first promote bitcoins amongst the libertarian crowd.
Be careful not to confuse your ideologies. Libertarianism and agorism are closely related, but they are not the same thing. Generally speaking, agorists are libs who have dropped the 'live and let live' non-aggression principle in favor of an intentionally subversive market stragedy with the intent of 'starving the beast'.
