In your example how do you tell renters you have a house for them?
If the answer is "some service like Airbnb that uses the blockchain", I'd contend that the end user really doesn't care what it's built on.
The service is the marketplace, not the legitimacy of the transaction.
The problem that decentralized services will always have is that someone has to make them, and those companies will lose out on all the benefits of a centralized system (primarily control). A centralized competitor will exploit those benefits with no detriment because again, users don't care what's behind the front end they interact with. Any company looking to build something is going to have a hard time explaining to free market investors why it is in their best interest to relinquish control for whatever the blockchain gives them in return.
