@Jim95 - As a normal, casual user on Airbnb, you cannot. Most of the properties with this designation are very, very high end - like renting the entire island level high end - and are very, very rare.
The Strict Cancellation Policy does pay you 50% if a guest cancels any time before 7 days ahead. Within the 7-day window, you get 100% payment. In either case, you're property would be open for rebooking and, if you book, you will get the payout from the cancellation AND the new payment (so, in effect - double). After a cancellation, Airbnb does move you up in the listings and they will promote your listing - especially if the area is heavily booked. In 2-1/2 years, I've not once had a cancellation that did not get rebooked so I got paid plus I got the cancellation payout.

There is, indeed, and Extenuating Circumstances Cancellation Policy Exception. It protects both hosts and guests. Perhaps you are not aware of the penalties for hosts who cancel. This policy, should you need it, will keep you from being penalized. People doen't just get to use it willy-nilly, they have to prove it to Airbnb and Airbnb makes the decision if the person qualifies for the exception.
