Completely nonsensical and screws everyone involved.

Student loans are supposed to be an investment the government takes in its population. If it works properly then the money that the government spent on the students tuition is both paid back monetarily by the student as well as societally because now you have an educated citizen providing ever increasing tax revenue. If you make student loans illegal you not only make it impossible for students to educate themselves beyond public school you destroy the entire post secondary school industry now that so few can afford to educate themselves.

What needs to happen is cutting out all the middleman bullshit and just making post secondary education free with your taxes, at least a couple years worth. If someone wants to be a doctor or a lawyer or someone who needs to have more than a couple years worth then sure that can be on their dime. Otherwise those first 4 years are just unnecessarily saddling people with mountains of debt that there is no guarantee they can pay back after they are done
