I've read in Longman English Grammar (PDF, page 258) that we use get and get / have+object+past participle in a non-causative way for accidents, disasters, etc. that happen beyond our control.
Don't join in the argument or you might get your nose punched.
She had her house destroyed in an earthquake.
I think using have in non-causative way is to use the experiential construction (Have+object+past participle usage).
But here in the first sentence get has also been used non-causatively.
Experiential construction shows the experience. So it's called experiential. But in the first sentence, the subject (you) hasn't yet experienced of being punched on his nose. But why is this sentence still in experiential construction?
Do we use have and get non-causatively in every situation when something happens to us beyond our control?
