If there is no national tax base to take over then there is no nation to defend. If people can defend themselves from domestic taxation then they can defend themselves from foreigners who want to tax them too.

The govt as an organization is nothing but a manifestation of the tragedy of the commons. Everyone just tries to get what they can, while they can, without putting in any work. It's people seeking to become a parasitic authority as a source of wealth rather than working to create value for others.

The divide between good & evil is the prioritization of the pursuit of truth vs the prioritization of the pursuit of status & power. It's not a coincidence that God in human form was a man who spoke truth to men of arbitrary political authority & was killed for it. I'm quite certain that a large part of the point (no matter how few people choose to see it today) is that men in govt, clinging to status & power, will destroy the truth & kill God to maintain it. God or reality or the universe (or whatever label people prefer) wants people to see that force funded institutions are evil, & the cycle will repeat until we learn.
