I wonder, if parents alone had to pay for schooling and there were no substantial student loans, how many students would get away with running amok instead of learning something valuable.

Fewer. Many fewer.

Most certainly; plus parents would be demanding a more intense and demanding curriculum for their kids and would probably sooner horsewhip their son/daughter if they wasted time on protests. Before student loans were widely available, students studied and didn’t waste time on protesting or behaving like trollops.
