Anissimov asked about neoreactionaries answering more practical questions, so I’ll float a few ideas.

Reservations

There are semi-sovereign communities in North America: Indian reserves. I’m not sure how these work in the US, but in Canada they are free (more or less) from provincial law and subject to federal law. While I won’t get into the specifics, Indian reserves do have some limited sovereignty. The laws would have to be looked over by a qualified lawyer but it might be possible for a reactionary community to strike a deal with a reserve to use a portion of their land free from many of the more intrusive laws.

Western and Northern Canada

Western and Northern Canada has an abundance of cheap, fertile land. If you’re willing to live an hour or two from the city you can get 160 acres of farmland for $80k or less. You can get treed land for cheaper; I’ve seen 40 acres for as little as $12k. Property taxes for these are usually a few hundreds dollars a year.

I’m not sure the cost of land in Idaho, but if that doesn’t pan out, the Canadian Prairies are cheap.

Conquering Nations

Mike asks, “what kind of private military force would it take to occupy and hold several islands in the South Pacific?”

For this, I would suggest looking to Bob Denard. He was a French mercenary who throughout the 1960’s-90’s repeatedly repeatedly involved himself in various African conflicts. He particularly focused on the small island nation of the Comoros, which he more or less controlled from 1978-1989. The coup that put him into power required 43 men.

Depending on where the island was and its inhabitants, a relatively small, but organized force, could take control of a small island nation. The main problem would be avoiding having a major power intervene. Denard’s plans all fell apart when France decided to reign him in.
