The average person can do more to influence a local mafia boss than they can to influence the federal government. Hell if you have a few dozen friends with guns you can actually
stop the mafia from fucking with you for as long as they stick around.
* Edit since I'm spent on replies : Sure you can name that one favela somewhere where a few dozen were beheaded by the mob. The idea isn't that you'll win 100% of the time, the idea is you have some chance. I raise your one unnamed favela with several unnamed Mexican pueblos where cartel was run out by campesinos w/ break-action shotguns and rifles. And the mere fact you actually have a chance at winning is often enough to get a counterparty to back off.
