If you mean federal student loans, they are limited to a certain rate of disbursement and they also have a cap. You can't be perpetual student because of the cap, and you can't tap it all out in one semester. But as long as the curriculum you wish to use it for is part of an accredited degree-seeking program it qualifies for the money. You can get quite a bit of money also, I got well over $60k and used a fair amount of it for flight training which was not for a degree at all. They send your quarterly check to your college and the remainder is sent to you to do with as you please. These are federal student loans, and I do not know much about other lenders except that they charge more interest. My guess is they will look at the cost of the curriculum you are proposing to get a degree in and make a limit based on that. So if avgas goes up 100% then they would put a 100% higher limit on the loan as long as it meets all the other requirements. Of course it still has to be repaid and if everyone defaults on their loan there will be repercussions, and this is no laughing matter because Citibank nearly declared bankruptcy largely because of student loan defaults last year. This is probably why the federal government has to subsidize student loans in the first place. The only real issue I think is whether the Embry Riddles and other accredited pilot producing colleges wish to continue to offer degrees.
