Durability is great, but availability is also crucial, unless your business can tolerate hours or more of availability outages. Let's say us-central1 is down for some reason (has happened a number of times), but your customer workloads need to keep running uninterrupted, so you fail over to us-west2. Where should your customer files, that need to be read/written for the customer workloads, be written then? If you kept them all in the region that's on the fritz, you've got upset customers, broken SLAs, etc.
