Wow. My PCs have never gotten that high level. In my world there are adventuring bands all over the place and if a King felt threatened he'd call in his archmage advisor and ask him to send a force to kill these upstarts. And if the PCs don't clear out a nest of trolls any number of other groups passing through town will do the job. Humanity is surviving. This "everyone is 0 level" nonsense (and yes I'm looking at you Gygax on this one) doesn't really work and no world I've ever seen developed would ever develop that way with such an assumption.Generally speaking, I don't "enforce the law" when it comes to PC behavior-- this isn't because I'm lazy, though I certainly am, but because my worldbuilding is based on NPCs behaving rationally unless otherwise specified.
Law enforcement is inherently a form of violence, and PCs inherently, practically by definition, have a greater capacity for violence than lawful authorities. If the local militia could take down the PCs without losing half the town, they could have taken out the nest of trolls themselves instead of hiring the PCs to do it. And if the king sends his armies against a force that can tear his armies apart, he knows he'll have new enemies and no new armies.
The law is no longer a concern for heroes, but reputation is everything. Heroes who help the common folk and seek justice are beloved by the populace and just rulers. Heroes who prey on the weak may not be subject to the king's justice... but they can expect no accolades, no gratitude. Heroes may not be under the law, anymore, but they are also outside of it-- noble or corrupt, they don't enjoy the law's protection, and must rely on the value of their word and the honor of their name to move in society.
So sure if the group is high level, then the local village elders are not going to be able to handle them. If they act with impunity though, eventually someone will come for them.
