Earlier quoted context omitted.
Am I missing something here? Paying cash doesn't prevent the opening of fraudulent lines of credit in your name. Equifax et al don't particularly care if you pay cash, they have some form of record on you either way.
if you use cash exclusively, then you have no credit to exploit. equifax knows about me, but no one will give me a loan.
While that should be the case, unfortunately, that's not true. And it may make you less likely to notice if someone does in your name.
