If you dislike society so much - leave it.
That's your option. You don't like a society with a social contract, you think you can take from what WE paid for and not help pay for it yourself ? Then leave.
I hear Mogadishu is EXACTLY what you are hoping for. Pinochet did it in Chile too but that's gone unfortunately for you.
What ? You don't WANT to live under brutal warlords or dictators ? Well news for you - ANCAP doesnt work - ANCAP always ends up being run by brutal warlords. And libertarian societies cannot even come to EXIST without a dictator to create them. That noted socialist Margaret Thatcher told F.A. Hayek she CANNOT replicate Chile's policies beyond the small bit she did - because it's not POSSIBLE in a democracy where the leaders have to actually answer to the citizens for their policies - where the leaders have to negotiate and collaborate with opposition leaders in the parliament.
So your dream cannot exist in anything resembling a free society. In a democracy - it can't be done. You can get the libertarian economics if you have a dictator but then you lose ALL the other freedoms. Or you can try the ANCAP way and, as it ALWAYS HAS, end up getting killed in the crossfire as the brutal warlords fight for control (coincidentally - those warlords don't give a fuck about your personal liberties either).
Basically - yours is a pipe dream. The only way you can have what you want is in a society of one. Maybe "one family" - any bigger than that and the entire thing falls the fuck appart. Just as it always has, every single time it's been tried.
The only anarchist state that ever managed to exist as a successful, industrialised economy - was a socialist one: Andalusia. The anarchism worked because there was no economic inequality from which warlords can arise.
