I didn’t say offensive force was moral. I said it is inevitable. Conflicts will arrive. No moral society will be so perfectly free of any social conflict so as to avoid it entirely. Criminals always exist, even in the most peaceful ones.
Anarchy does NOT produce peace. There is no such thing as an anarchist society that remains peaceful for long. Inevitably, 2 or more groups disagree on something and then come to blows. The court system of a government is meant to dissipate this natural human tendency.
The problem is when the courts become the WEAPONS of an immoral state, ignoring criminals whilst dissipating your moral Revolution against them.
