While I appreciate the attempt to reconcile all legal matters concerning cryptocurrencies, I do not think the laws of the US applies to all sovereign jurisdictions. Nonetheless, I know for a fact that there are laws that are general in nature, like for instance, common laws; yet again, we have varying laws per State vis-a-vis the policies of ones government and one cannot be made to apply to the other. So, as for me, I think it is still best to consult your local counsels for legal matters.
I have never made any claim that I could "reconcile all legal matters concerning cryptocurrencies," nor would I ever make such a ridiculous claim. Of course laws are different in different countries and of course laws vary state by state. I only offer advice for matters in the United States. If I believe that there are state specific laws that may apply I always make note of that where appropriate. There are however many laws that are federal or apply to most states similarly, in those cases I attempt to offer what I can and no more.
You have made a point regarding obtaining local counsel, which is always a good idea, but you have made your point by making false statements and assumptions of what I have and have not answered here and that is inappropriate and misleading.
