CP system is about not working when it is not available, otherwise you have no consistency at all and it is in fact very important to consider the whole system, not only the database part. Eventual consistency lets you fetch and store a tiny view of the database in the client and allows the user to work completely within the local storage, synchronizing with the global storage only when the internet connection is available. Which enables fast and always available user experience.
