I think what he means is that protection orders only matter to people who care about such things as protection orders.
Domestic abusers and aggravated stalkers don't seem to be terribly concerned about pieces of paper.
Given a choice between a piece of paper, or a gun, I'll take the gun. I'll add to that good locks and lighting, and a couple large dogs. Collectively, that's much better protection and deterrent than any writ would be.
