Let's say YC funds a 19 year old who bets everything on his startup instead of going to college. The startup fails and he has nothing to show for it. This puts pg in a bad spot, since he enabled someone who could be deemed a kid to screw himself royally.

I don't think it's a likely scenario though since getting accepted to YC and running your own startup should be enough of a merit to get you employed somewhere.

However, out of all the people accepted into YC there has to be at least one example of a person who not only did worse by doing a startup early on, but actually hurt himself pretty badly in the process. Of course, this is pure speculation, and there might not be any such cases.

Basically my theory is that pg just doesn't think it is worth it to potentially have blood on his hands (indirect as it might be).
