Sounds like you don't know much about this. That's why estimates are as high as a half-trillion dollars in new debt for student loan forgiveness. It has to be paid somehow with or without any gold standard.
The reason college costs so much today is because of supply and demand, meaning we have way more kids in college than we actually need. That's why some graduate and can't find work in the field of their study like my niece. I'm a retired truck driver and I can't tell you how many other drivers I came across with a college degree. They gave up seeking a career in their line of studies to drive a truck because it paid much better and a ton more job openings.
So there is no need for taxpayers to foot the bill for college. College is an investment. An investment is when you use YOUR OWN money, hope to get it back with a profit. Not all investments are guaranteed and many times you can end up with a loss. But that's the gamble you take when you make any investment. But for those that made wise investments, their payoff will be making much better money than most that didn't attend college.
If we get to the point we don't have enough kids in college and we really need them, then we'll talk about government. Until then, you want to go to college, you pay for it, just like I'm paying my mortgages, just like I paid off my car, just like I paid off my credit cards and home equity loan.
