Ugh. This thread is stale at this point and I know I should just walk away. As you said, we're having a purely semantic argument.
But the thing is, the semantics of words like "illegal" and "illegally" are extremely well established, and you've got them wrong. When you say that a person has done something illegally, you are saying that the doing of that thing constitutes a crime -- that performing that act explicitly violates some statute.
There are no laws against generating bitcoin or emailing your grandmother. Those acts themselves can never be done "illegally." If I break into your house, beat you senseless with a lead pipe, use your computer to email my grandmother, and then swipe your cash and run off with it, I will be charged with (and guilty of) several things when I am caught: breaking and entering, trespassing, aggravated assault, unauthorized use of a computer, and robbery. But not with emailing my grandmother. There is no law against emailing my grandmother.
Anyone with even the tiniest exposure to matters of law can understand the distinction here. And I'm not saying that you don't, by the way -- I know that you understand my contention just as I understand yours and we are in disagreement over semantics. And if you want to assign a meaning to the word "illegally" that differs from the accepted meaning that's your business.
But don't act like the rest of us are the ones being obtuse.
