I agree that "natural keys" in database, or other data structures, are
often not a good idea. You can arrange for a unique ID your application
chooses to never change. I've seen the following change, in my career:

* Unix username
* Unix uid, without changing username
* SSN
* passport number
* email address
* company registration number
* several companies with the same registration number
* street address, without recipient moving
