You can establish rules peacefully in your neighborhood without the need for taxation and a police force. HOAs do this all the time. They have security, even if it's just a gated community. They have certain rules that can lead to fines or eviction when violated. In a free market, you can find the type of neighborhood that fits your needs. If you need less security because you have guns and dogs, then you can save money. If you have a family, then maybe you wanna pay more for a more secure neighborhood with a security car driving around. I've lived in a community with a security car patrolling at night. Whatever service you need, you can find it cheaper and more efficient in the open market.
