How so? The benefits are worth it, and I doubt any CEO will be argue against having fault tolerant code :)

You catch bugs, and no one says you can't run Chaos Monkey in staging or a similar environment if it really is a tough sell.

The drawbacks of potentially causing downtime and therefore having the potential to drive away customers as well as obtain an image of unreliability can be much more damaging than not using it in the first place. Customer image means quite a bit.

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).
