In your example how do you tell renters you have a house for them?<p>If the answer is &quot;some service like Airbnb that uses the blockchain&quot;, I&#x27;d contend that the end user really doesn&#x27;t care what it&#x27;s built on.<p>The service is the marketplace, not the legitimacy of the transaction.<p>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&#x27;t care what&#x27;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.
