This would be one way to do this, yes, and I think it would be overall good for society if there was a clear association of cryptocurrencies and crime. There would still be shady cryptocurrency things (just like we still have illegal drugs and gambling and prostitution), but at least we won't have smart people proudly announcing that they made new crypto system (just like we don't have people proudly announcing they made a new kind of illegal drug today). Because for each person who genuinely believes into monetary anarchy and/or does not trust the government, there are lots more (thousands? tens of thousands?) people who read about it in New York Times and want to earn their money. It is the second group which is fueling the first, and so getting rid of it will make crypto harmless again.
