For me a ban means no coins can transact, i.e. it is legal action that requires an unknown justification. Rather blacklisting would be a different legal action that has established justifications already in AML, KYC laws, etc.
Okay difference of terminology then. I have been referring to a "ban" as a ban on anonymity, and a ban on anonymity as being a effective ban on a coin that has as its primary merit anonymity. Sure there are unblacklisted coins being mined, by why would anyone even want them?
I did not say anything about the value and price of the coin after such an action. I was distinguishing between a ban on transacting (which seems to be legally more difficult) and a blacklisting (which seems to follow more easily from admirality law, AML, KYC, etc) which is effectively a ban on ring signatures.
We agree that if a ban on anonymity is imposed and is actually effective, then there will be no anonymity. To me that is fairly obvious and uninteresting.
But my overriding point is that to protect anonymity and fungibility, mining needs to be impervious to control by the State. If that isn't possible, then I wouldn't waste my time on anonymity.
