the later inherently implies using violence to suppress people
All laws that you want to be strictly enforced, requires violence. This is why people should ALWAYS remember when making laws: "Is this worth killing for?"
I remember some years ago on HN people discussing about a guy that got killed because he bought a single fake cigarrete. IT goes like this:
You make a law where "x" is forbidden, penalty is a simple fine. Person refuses to pay fine. So you summon that person to court, make threats of bigger fine. Person ends with bigger fine, refuses to pay anything. So you summon that person again, say they will go to jail if they don't pay. They again don't pay, AND flee the police that went to get them. So the cops are in pursuit of the guy, he is a good distance away from the cops for example, then they have the following choice: Let him go, and he won, and broke the law successfully... Or shoot him, the law won, and he is dead.
This chain ALWAYS applies, because otherwise laws are useless. You can't enforce laws without the threat of killing people if they refuse all other punishments.
I don't know if the guy you were discussing with is right or not, if digital era result in the need of "ruling with the iron fist", but make no mistake, there is no "strict law enforcement" that doesn't involve killing people in the end.
Thus you always need to think when making laws: "Is this law worth making someone die because of it?"
Your whole post falls apart right there.
Person 'x' refuses to pay a fine - OK, well there are mechanisms where a fine can be automatically applied in some cases, or taken from their assets by court order, or docked from pay. In some places bailiffs/repo men can be called to take assets after fines have been delinquent for long enough.
Deadly force is not really the backstop position to a fine, even a 'strictly enforced' one.
Nevermind cases where people don't even have a bank account or anything you can take. Or they protect it well enough.
Physical force is permitted against nonviolent criminals so they can be apprehended, but lethal force is usually not permitted unless the criminal has used or is about to use violence.
Yes, there are of course instances where nonviolent criminals have been killed, with that act of killing being legal under that framework. For example, if a criminal is escaping in a vehicle recklessly and putting the lives of others in danger. Or cases where enforcers are given overly broad latitude in determining what constitutes a threat of violence. Or tyrannical regimes that authorize lethal force for minor infractions.
But it is not the case that most legal systems say “a criminal can be killed if they refuse to submit to punishment, regardless of the severity of their crime”. That is a misconception. People don’t get killed for not paying fines, they get killed for trying to shoot the person that comes to take them to jail for not paying the fine.
