Do you say the same about cash? I am a fan of some molecules the government has erroneously classified as having "no medical use," and I tend to acquire these via cash routes. So cash also enables crime. Do you think we should transition to a fully networked currency that has perfect auditability for all transactions?

I'm sincerely asking. That appears to me the endpoint of the argument you make here. I might be wrong in my interpretation or conclusion, so please do correct any inaccuracies or leaps you find in my post.

I am not a fan of cryptocurrency, because I think it is stupid. But I am a fan of (actually) anonymous and privacy preserving currencies. So I can continue to not harm or victimize others, but acquire the molecules that make me the most functional.

This is certainly an ideal that libertarians hold, though I do not claim myself or my views as being particularly libertarian.
