I have no idea what your point is. The monopoly of violence stands behind literally every law on the books. Going down the rabbit hole on the particular example of fines is missing the forest for the trees. If you have an issue with the monopoly on violence being behind ultimately behind the government fines, then you have an issue with organized society itself.

But we have a whole set of other measures - fines, penalties, negotiations, loss of benefits - and institutions to enforce them before ever calling upon the actual violence provided by the monopoly for a reason: so that most common societal infractions never need to escalate to the point of violence.
