We all like gold however everyone is aware of how fast it is gone through. By being able to put coins into the Tavern it'd help us save and also in case of emergencies. I realize that this is similar to the clan chest. However the clan chest can be accessed by multiple people. This way we can keep some gold separate and safe for whenever. We can already put items in the tavern; it's logical to be able to put coins in there as well.
