Agreed, it should be hard to explain benefits even to non technical people. It's like doing a fire drill, if you do it frequently when the actual fire happens you will know what to do. Similarly with infrastructure, it might not be good handling rare events, but once these events are not rare you will learn to handle them.

The biggest issue IMO is explaining need to make things more resilient. Actually the technical people (mainly developers) might be the biggest obstacle, because it adds more work for them (with no visible benefit to them, because when application fails it's ops who get woken up).
