There are two reasons.

One reason is that I was distributing multicast with a Cisco router
doing the fanout. With a tunnel, you put multicast in one end and it
comes out the other even if the intermediate path doesn't handle
multicast. The other is that the end points all had private addressing
which the terminating equipment understood but not the intermediate routers.
