Hmm tell that to the people of Naples - the mafia are still in charge there, the pile of rubbish is one of many physical manifestations easy enough to see- talking of which careful where your mozzarella comes from.

Though you may be right there has been a crackdown- the Italians are on the brink, the mafia have more money and a closer network ... than the Italian government.....  I think you are also right that it will be impossible to stamp out completely or even meaningfully for quite some time.

 
Edit:  Talking of organised crime adopting tech- I see a world where illegal drugs are delivered by drones - cryptos could be a part in that , but more worryingly would organised crime need to use contract killers, (teenagers as is the craze atm)  buried exploisives/carbombs to take care of a problem- when they can send a weaponised drone over to see you.... (in a robot voice- "Gimme the f'kin BTC!!" electric shock) yikes.
