> Therefore before 2005, banks that lent money for student loans did so without that particular extraordinary protection.

Most of the pre-2005 loans required a parental co-signer. And I know that I wasn't able to take out non-federal loans all by myself.

Yours is a true statement that doesn't contradict what I said. Namely that until 2005, banks were lending to students without protection from non-payment during bankruptcy.

In fact the fact that banks insisted on mitigating their risks with a co-signer is actually supporting evidence FOR what I said.
