The Shire Free Church is attached to a whole vision for a new Shire Society, with its own declaration of rights:

Shire Society Declaration

WE, THE UNDERSIGNED witnesses to the lesson of history — that no form of political governance may be relied upon to secure the individual rights of life, liberty, or property — now therefore establish and provide certain fundamental precepts measuring our conduct toward one another, and toward others:

FIRST, each individual is the exclusive proprietor of his or her own existence and all products thereof, holding no obligations except those created by consent;

SECOND, no individual or association of individuals, however constituted, has the right to initiate force against any other individual;

THIRD, each individual has the inalienable right of self-defense against the initiation of force;

FOURTH, explicit voluntary association is the only means by which binding obligations may be created, and claims based on association or relationships to which any party did not consent are empty and invalid;

FIFTH, rights are neither collective nor additive in character, and no group can possess rights in excess of those belonging to its individual members;

We hereby declare our commitment to peace, individual sovereignty, and independence, and join the Shire Society.

The immigration page contains an explicit articulation of New Hampshire as the libertarian dream destination, specifically Keene and Manchester.

While you can be in the Shire as a state of mind, it makes sense to live close to others who believe as you do. You are encouraged to immiGREAT to the Shire.

This all ties together their intentions into a pretty cohesive and well-organised political vision. From Wikipedia:

The Free State Project originated from a 2001 essay by then-Yale University student (and later lecturer at Dartmouth College) Jason Sorens. The idea behind the project is to get 20,000 libertarians to move to New Hampshire, a state with a low population where a group of that size could yield significant political influence. By 2014, about 1,500 libertarians had already moved to the state, and several "Free Staters" have been elected to the state government, including Andrew Prout of the New Hampshire House of Representatives.
