Of course. Nothing in life is guaranteed. I'm sure the Buddha would tell me that "there ain't no such thing as permanent". Nevertheless, I've had my domain name longer than I've had my current phone number. I'm far more likely to put up a fight for that name than I would be to fight for the current string of digits that represents me in the phone system. Maybe the whole concept of user-owned identifiers is a myth, or a Platonic ideal. At least in my case, my phone number is pretty far from the Platonic ideal.
