As the Bible doesn't allow anarchy, I cannot be a thoroughgoing anarchist, though under my own fallible wisdom, that would probably otherwise be my inclination.
If total anarchism can be proven to me to be compatible with biblical Christianity, then I'm there.
As it stands, though, I'm compelled to be a Minarchist. Within the Minarchist sphere, a constitutional republic seems to be one possible option - though seriously flawed, it sure would be a lot better than what we have here and now. But I'm by no means so devoted to constitutional republicanism as to call myself a constitutionalist.
I think that, in whatever form it may take, a government, by consent of the governed, that exists SOLELY for the purpose of defending all people's equal rights to life, liberty, and property (and is therefore funded not by taxes but by voluntary donations), is on the whole acceptable.
The problems of force and violence plague anarchy as much as minarchy, monarchy, republicanism, and empire -- though clearly we should strive for as small a stage as possible on which violent people can be capable of acting. This is because the problems of force and violence plague human nature itself, and no political system can erradicate them.
Just thoughts.
