Every single usage of Bitcoin is illegal in one form or another in at least one jurisdiction. That is why it clearly needs to exist. For example, Bitcoin seems to be outright banned in China, the most populated country. Obviously this makes China an overtly evil country without proper moral values.

Under Caroasi-based law one of the only possible illegal usages would be to pay someone to help commit a violent crime. Caroasi can start off as an internet government as soon as one person joins. I won't be the first but I'll be the second person and reserve that honor of the first person to perhaps someone on this forum. Caroasi just ignores illegitimate governments laws as irrelevant. No country that bans a moral usage of Bitcoin should be considered a serious country, as laws that violated higher or highest laws are not serious in sense even if they are violent.
