A society which only has low crime because everyone is able to use lethal force to defend themselves and their property isn't one I would call higher "trust" than one that maintains the same crime levels without that threat.
The end state is you can trust others because nobody even wants to or considers it.
Punishing violators is being proposed as how to build the norm that no one wants to steal.
So, either citizens bear force, or they plead with the government to wield their force. But, force is there, either way, keeping people in line. It has never been any other way.
