Most insurance is invalidated by operating outside of the very narrow boundaries. For example, car insurance is often invalidated by driving for uber. If you're generating revenue from your property (home, car) then you need specialist insurance which is much more expensive for this very reason. Presumably the author of this story chose to believe the most convenient version of reality: that Airbnb's "AirCover" was a suitable replacement for landlord's insurance -- but it is not reality, oops.
