As for who enforces it, there are mechs... though the most common method of death would likely be impossible solo missions of the "fight till you die" variety.

As for "anyone can train to be a hunter" this is true, however that would not be what this rule is for preventing... it is specifically for preventing "dynastic" or "clan" rule. Realize that in remnant a hunter "family" would be like multiple generations of "Mr. Rodgers" a family full of elite warriors who also enjoy a large amount of popularity that most politician's could likely barely dream of... like gladiators of Rome that actually "defend" the realm.

With your last point, we have been led to believe a "revolution" is about to occur, yet remnant in general seems almost utopic(other than grimm, which seem to be less a threat with each episode and are unrelated to kingdom policies at this point)... the insanity of the rule would be a catalyst for a new war
