As a lender, why would I loan tuition money to someone enrolled in "gender studies", "negro studies", or any other "studies" program?
Exactly. In a free market, you wouldn't do such a thing. As a private lender in a free market, you would know that it would be a bad loan, unlikely to be repayed.

they lend because there are protections for lenders (such as debtors can’t clear their debt through bankruptcy).
What they should do is return student loan debt to the status of a normal unsecured debt (like credit card debt) for any future loans. But the government should be prohibited from being a lender, all lenders should be in the private sector, and those private sector lenders will have to absorb the loss of any defaults. If we can create a market where only credit worthy borrowers will receive loans, than lenders are unlikely to give loans for nonsense-type fields of study.
