The real threat is big banking institutions laundering money for drug cartels and terrorist groups with absolutely no legal repercussions, apparently. We don't even track or enforce rules for banks funneling funds around using hard currency as it is, why the hell focus on bitcoin? Hey, here is s quick history lesson - do you remember when ISIS was at its zenith, at its most powerful a couple years ago? Do you remember what started it's continuing downward spiral? They dealt only is cash, so intelligence services figured out where their actual pile of cash was, and they used a combination of bunker buster and incendiary bombs to destroy their literal pile of cash. Terrorists don't use bitcoin, they use cash, because cash cannot be traced.
