There is no need to connect to a moib server to authorise anything.
No mobi server means no new devices.
Scenario: books are backed up and moved to a new device. You no longer have any previously authorized devices. If the servers are down you can't authorize a new device for your existing and already downloaded files. With ereader as long as you keep a record of the original CC number and name you can still read them on any device.
Having the mobi encryption servers go down can lock you out of files you have already downloaded if you need a new device. With ereader you can still read those files.
