This is exactly the fantasy that we need to dispel, not rationalize.
Nobody steals your identity. You always have your identity, and nobody else ever does. Your identity is not the few pieces of trivia a criminal can easily discover about you.
The criminal never takes or has your identity. The bank is simply neglecting to correctly identify someone.
> steals that identity to abuse it
Criminals are not abusing your identity, they are abusing the banks' careless failure to correctly identify people.
> to abuse it and leave you with the baggage
The criminal is not leaving you with the baggage, the bank is. They use willfully inept processes, because they have tricked you into believing you should bear the responsibility for the consequences of their own hubris.
