Not entirely correct, if you read about panarchy and contract jurisdictions and georgism and NAP, you might see that mostly they approach the same point of the river flow, just walking on the other shore, so to say.

We can agree on libertarians being the whole spectrum from “vegetarians” to “vegans” in politics, and left anarchists being only in the “vegan” area, if you will.

Still,

The real political vegans are those who go off to form their own communities and reject the ENTIRE political structure, not just the parts that don’t directly benefit them.

• such libertarians exist too, and the more radical part of them is fully of this kind.
