The mere fact that it's becoming possible to make comparisons between a Western government and a criminal organisation, even if it's just to get a message across, is worse enough on its own.
Of course, a government has the power to brand a mafia as a criminal organization, but the line between legal and criminal can be very blurry, and often quite arbitrary.
If you just go, historically, by the score of committed crimes, then whatever metric you choose, governments and their agencies will beat criminal organizations by a huge margin.
Bullshit.
You'd do well to read more about the Mafia and how it affects places where it's strong. They are badly governed, and generally not good places to live or do business as an honest person.
Denmark has a strong government that is quite involved in its citizens lives, but the number of them that end up dead, tortured, with their lives ruined, and so on is minimal compared to people in Sicily, Calabria, Campania, or other areas in southern Italy dominated by Mafias. And the standard of living is far higher. People are happier; with the possible exception of the climate, which is not really something either Mafias or anyone else can change on a local level unless you read some of the wackier subreddits.
Mafias are nothing like western democracies. If you're going to compare them with governments, compare them with feudal, tribal systems where family and personal loyalty is everything, and the rule of law counts for nothing.
To equate even something so abhorrent as fascist Italy to the Mafia is to have a gross and severe misunderstanding of history. They are both bad, but very different.
The Mafia is a real thing here in Italy, not just some abstract talking point for your libertarian ranting.
