You keep bringing up examples of things that harm people, and talk about using force to stop that. "Government" is NEVER limited to such defensive force. It ALWAYS uses immoral aggression, in the name of "taxation" and "legislation" and "regulation." When someone commits force or fraud, ANYONE has the right to do what it takes to stop that. It doesn't take politician scribbles ("laws") or special "authority" to make it justified. If you really meant your final answer to that final question, you are ALREADY a voluntaryist, and don't know it.
