Yes, it can be difficult to imagine for some people, based on their lived experiences. Those who have observed little or no unwanted behaviours from short-term renters wild tend to assume "It works." or "It works the vast majority' of the time.". Some combinations of hosts, their rules, and guests can be successful and completely non-problematic. I, having lived some problematic places long before AirBnB existed, sympahise with your experience. I've been fortunate to see primarily successes.
