Nicely written and for the most parts correct, but there are reasons for crime. There are also with cash, but with cryptocurrencies it is faster and safer. Recently I read a report from drug cartels in Colombia, who are happy that they no longer have to send cash in bags. With cryptocurrencies, it takes just a few seconds and deals are supposed to be quick. It has become easier for them to send the money, but not the drugs.

The same is true for cash and I would bet that every one of us has illegal money in our hands. The money may have been used in illegal deals in the past, but we dont know.
