Would you expect enforcement of compliance to be handled by the same people that are 'handling' it today?

Depends on the flavor of libertarian. Being you asked me directly, as a Minarchist, I would expect something similar to current policing to enforce actual criminal laws (let's say if someone pulls out a gun and shoots someone on the road) while the entity that owned/managed the road would handle enforcement of their own internal rules and policies.
