There is a key issue regarding legal tender which might help some of the explanations here.
If a Bitcoin issue ends up in a court of law in a country that has a legal tender law similar to the USA, (most all countries), litigants are required to accept the legal tender of the state, in any dispute, as full compensation. (This is the effect of "Good for all debts public and private")
This means that anytime a court is involved, the bitcoin can be sold and the government cash substituted as payment in full to whomever wins the case. The value at time of transaction in the local fiat currency will be the important point to determine the amount, and should be one of the facts determined by the court.
Perhaps you could expand on this?
