Why the "but" ? If you explain to someone how to install a crypto wallet on a computer knowing that this installation will help that person do tax fraud, then you're an accomplice to tax fraud; and if you explain to someone how to install a crypto wallet on a computer knowing that this will help DPRK evade santions, well, that's a crime on its own. Telling others how to do simple things (that they could find on the internet on their own) and providing trivial, simple help may be a crime depending on the intent. There's no requirement to provide some unique, significant, irreplaceable insight or service, knowingly providing any help whatsoever is sufficient. Helping a buddy wash his car is a simple, nice thing to do; but helping a buddy wash blood off of his car before the police gets to it is a crime.
