Hello Iakovos, I don't think this means Airbnb doesn't give a **bleep** about its hosts.
On Airbnb people matter. If there is an exact same places, but two different hosts, with different behavior, and different way to take care of guests, the listing changes.
Reviews are not only for the listing, but also for the host who takes care of them.
So there's a reason why you can't transfer listings as you want, and I believe this is the reason. I have to agree with Airbnb's policy on this.
What if I have great reviews, but I sell my house to the worse host ever. Why would he get my reviews? This would be misleading for guests.
