So sounds like the bug is lax enforcement of noise ordinances? Not sure why it makes a difference whether the drunk and noisy houseguest is a short-term renter or a friend of the owner.
A friend of the owner implies the owner is a neighbour, someone who you can eventually talk about the issue in the house. It makes a difference as there's a greater degree of social bond (and consequently shame).
Are you being obtuse on purpose to not give up on a flawed argument?
