There's really no problem you can't solve, with the law or otherwise, by paying people to commit violence on your behalf.
It keeps getting proved over and over that first world, well off countries can't pay or train or subjugate other cultures into civilized engagement with the world or even their own people. Nation building is an awful joke of a policy, and at some point people have to figure their own shit out.
There are legal and illegal immigration and asylum possibilities all over the world, or you can take up arms against corruption and tyranny. It sucks, but being born doesn't entitle you to anything unless there's a culture and civilization to make good on those entitlements.
Taking up arms is thr easy part mate, there is no shortage of thay going round. creating a functional society is the difficult one.
To pretend this can be easilly achieved is just folly
Then, one day, a small group of thieves starts entering and assaulting stores, trying to extort people and robbing others on the streets, threatening more violence if people don't cooperate better. You try calling police, but they either don't show up at all or only do so late and never investigate anything worth a damn (remember, they collude, and they're likely colluding with your newly arrived local thugs).
So, your neighbors and you organize together and ambush these thugs the next time they come along with their attempts at violence. You catch and badly beat a few of them then toss them out into a public area where an ambulance can pick them up. It sends a clear message, the extortions stop.
Is this ideal? Nope. It's awful, but you want peace for your business, community and family, and what other recourse do you have? Should you and all your neighbors just spew platitudes about ideals of law and order while being assaulted regularly? Or should the whole neighborhood, as you say, apply for overseas asylum and wait months or years for a response (likely negative)? Maybe they should abandon their homes and everything else of their culture to illegally flee, letting the country sink further into chaos?
They mostly won't do these things. because they want a peaceful home that is their real home, and with legal options having been marginalized, communities and groups sometimes really, no-shit-no-other-option have to take matters into their own hands.
Maybe that clears things up about perspective from within a highly functional, lawful country that had decades or centuries before you were born to become like that, letting you simply enjoy it and criticize others who aren't so lucky yet.
I'm not criticizing the people who find themselves in shitty situations. I'm criticizing your statement that the civilization I am fortunate enough to live in is "privilege." It is a carefully guarded and deliberately constructed civilization designed precisely to defend individuals from mobs and strongmen. That is a right, not a privilege, secured by violence and death and sacrifice.
When there is no rule of law, might makes right. Securing civilization from lawlessness universally starts with blood and death and is a horror show. It's that, or leave for a better place. By staying, you're giving power to the exploiters. Worse, you're giving them the means to abuse and exploit more people, and more generations of people.
There are no good or easy choices in such situations. You kill, you leave, or you perpetuate the hellscape, inflicting it on your local society.
The idea of the state having a monopoly on violence is the foundation of all successful civilizations. The idea being that if there is no monopoly, the right and responsibility to use violence falls to individuals, and when individuals are wielding violence without consequences, rule of law is meaningless.
Staying isn't just a casual preference for most people, it's a basic economic necessity and an emotional attachment to the idea of not giving up and ceding one's home to abusive people because things got tough.
People aren't normally thinking in some abstract sense that "I should leave this country and stop giving abusive social elements the means with which to perpetuate themselves". They're more often thinking. "This is my home and where my family is from, why should I flee everything I know instead of fighting back however I need to?".
So stuff like people being declared dead incorrectly, identity fraud. I'm also reminded of an incident in the Netherlands that lead to the fall of the current (still acting; it's complicated) government, where the tax agency was somehow convinced people had fraudulently received particular subsidies and decide to get the money back plus interest, which it turns out tax agencies are very good at.
Good luck finding anyone to beat up there. You can scare people but you can't intimidate red tape.
The history of Scientology versus the IRS suggests otherwise.
You'd have to band together with other people like you to stop them. I guess you'd also need some mechanism for restraining the worst impulses of the mob we've just organized, like a governor restrains a steam engine. We could call it a "government." I bet it would be a hit.
You can't solve violence without violence.
Failing to differentiate between these things makes me wonder are you some sort of animist?
Unless you are claiming that cutting someone's paper is equal to cutting their skin?
