Totally nonsense bitcoin destroys the state, you're trying to adapt the concept of state to bitcoin which is even more nonsense.

Neither of those is an axiom. They are pretty common results of analyses on those topics.
Bitcoin is not a state not because states are evil and btc isn't, but because btc doesn't fit the definition of a state. (see my reply above)
"...and self evident" is the important part. Both is evident after an analysis, but neither is self evident.
An example of an axiom is that "water is wet" as just by definitionsof water and wet this statement inherently and inevitably proves itself true.
Given that the concept of good and evil relies on morality which is inevitably subjective, no such statements can be axiomatic as axioms do need objective estabilishment of the truth.
You may call it a presumption and I won't have any issue with it as I agree with both statements, but they simply are not axioms.
