Zoners - why they do exist?

[The Savage]

Sounds veeeeery doubtful, but I guess I better not argue about it here.

It's more about common sense in here, as if you have someone neutal, why to have even more problems in already hostile system such as Tau-23. No army can win against the enemy which knows its own neighbourhood.

Remember that majority of Militaries can act inside bordering systems, if we are speaking about rules. Check every house military ID. Liberty can act in a very same manner inside Kepler as in New York.

- Can demand contraband and levy fines within their Zone of Influence, and attack if ships refuse to comply.
- Can attack ships which are in violation of Liberty laws or belong to a house or organisation considered hostile by Liberty within their Zone of Influence.

Zone of Influence: Liberty, systems directly bordering Liberty, Hamburg, Leeds, Newcastle, Manchester, New London, Dundee

And roleplay-wise, Kepler and Hudson are entirely owned by Liberty, otherwise I'm not sure why I see Trade Lanes belonging to Liberty Navy. Just a small point here. However, I do agree, according to the Law Codex, they do not claim systems like Bering, but we all know situations, in which one thing is on paper, the second is in action.
