Instead of thinking of societies defined by a certain ideology, think of individuals guided by their own internal moral compass. If you want a society where nobody commits acts of aggression against each other, the only way to get there is for the great majority of individuals to believe that such actions are wrong. You can call such a society an ancap society, a free market society, a voluntaryist society, a utopian society, etc. The name doesn't matter, what matters is how individuals act towards each other.

There is no guarantee that such a society wouldn't be infiltrated either violently, or subversively, by individuals (like statists) who believe aggression is justified just as there is no guarantee that any form of statist society will exist in perpetuity.

Regardless of what other individuals do or believe, you can still act morally (without aggression) toward others and escape from the aggression of others to the best of your ability. For example, you can find ways to legally escape taxation. You can choose not to use the services of the state as best you can. You can interact with those in your interpersonal circle without coercion and violence. You can practice virtues (integrity, hard work, kindness, conscious awareness, etc.) that empower and enrich you and others, to produce wealth and to spread peace and prosperity.

An Ancap society doesn't necessarily have to be a geographical location. Through the internet, local meetups, conferences, etc. you can choose to surround yourself with other like-minded individuals and spread the good word of voluntary, peaceful interaction.
