I see a description of how to access headers here, but can’t seem to find any examples of where they are useful. Some tutorials include code that access the headers, but without any explanation of why. Can anyone shed any light?

It may be the case that you need to send some information with the message that is not directly related to the body itself. This is a similar concept to HTTP headers. An example of this would be that when a message is forwarded to the error queue, there is some information sent along with it to help you understand what went wrong(including the exception).
