What do you imagine the state uses to compel obedience to its laws, if not threats of violence? Sometimes that violence might be appropriate, but some firm sending you an unwanted email falls short of the mark.
Violence can also be confining someone to a jail cell, or confiscating (taking without voluntary consent) some or all of their property (e.g., imposing a fine on a person)
Your modern Australian courts must do this, to compel compliance with their decisions.
If you lose a lawsuit and fail to pay, then they just come and take your money and/or your possessions. If you attack the sheriff's deputies carting off your stuff, or assault the bank manager for having given away "your" money, then yeah, you are in for a world of hurt.
