As for something about "good luck dealing with nomads when they attack" which I believe Jeremy Hunter said... I do believe that folks in the Liberty Forces are numerous enough to deal with most concerted attacks and they certainly do not pull punches with characters that talk about levels of light as a justification of shooting.
Plus, the entire reason for such a ID block would be to stop the Order from using it as a transit point to the rest of central Sirius, and to stop traders from even trying. As I said, there's a jump hole to another place there, go through there if you really want to get to Liberty. It's not meant to be easy to get from Minor to New York, nor is the decision meant to be one that can be made on a whim.
