and utterly unnecessary. Security shouldn’t automatically read military - an police/gendarmerie like force would be wholly sufficient with limited powers of arrest and hold, and a mandate to protect the physical integrity the stead. I would also make service mandatory due to the nature of the stead. I have to stress this is not about building an offshore police state but rather ensuring that security and protection remain in the hands of the actual residents rather than a dispassionate security company and/or security services of another nation state.
However any security force would/should be based on the legal and governance framework the stead adopts.
