“Most people who get an RO typically are violent, angry, dangerous etc.”
You are wrong about that.
During divorces many lawyers tell their female clients to get one. It is standard operating procedure these days.
Not only divorces. First there are temporary and perminent restraining orders. Temporaries have not proved anything because it hasn’t been reviewed by a court yet.
Restraining orders are used in a variety of contexts, including employment disputes, copyright infringement, and cases of harassment, domestic abuse, and stalking.
Second, a temporary can be in place for months while waiting for a court date. So, if a R.O. can now disarm a person unjustly, this is open for abuse by anti gun activists.
Third, if anyone was really a threat, commitment papers can be obtained immediately.
