It doesn't say anything about the moral hazard of paying off student loans for those who haven't paid them, while ignoring those who have. Or about the likelihood that a student loan cancelation will need to happen again. Or that those two things together will encourage people not to pay their student loans in the future, hoping for another cancelation. Or that universities will be able to raise prices even more because they expect further cancellations.
Sure, the deficit may not go up as much as naively you'd expect it to. And we won't have to pay it off with taxes immediately. (we'll just have more debt instead). But you seem to not care about all of the reasons that people oppose this, and just throw a pdf in their face, hoping it'll shut them up even when it doesn't argue what you want it to argue. Please stop.
