Eh, I'd say it's a bit more complicated than that.
Quite often the impersonator had nothing to do with the collection of the identity itself. There are people that 'copy' things like insecure online information around identity, but there are also people that physically steal things like drivers licenses and birth certificates. This is the stage of a crime that I'd consider actual identity theft. After that you have black market information brokers. They didn't capture the identities in the first place. They don't directly use the information to impersonate others and yet they are still complicit in a crime. Then you have the final stage of impersonation fraud as you state.
I want to be pedantic, it is not the identity they’ve stolen in the first case, but the documentation of the identity. A person’s identity is just intrinsically part of the person.
>A person’s identity is just intrinsically part of the person.
Is it?
If I look at least somewhat like you, grab your ID, and stuff you in an incinerator then any ID system that does not take detailed biometrics will have no clue if I'm you or not.
Saying identity is intrinsic is tantamount to saying "I am that I am". I mean, that's cool and all, but that tells me nothing about who you actually are.
There is nothing intrinsic about your name for example. This can and does change for people.
Again, same with location where you live.
We spend our entire lives grown up and getting old, so how we look adapts.
Then you get down to bio markers like fingerprints or dna, but these are recent inventions when it comes to human identification and take a fair bit of technology to use successfully.
