I came in here to make exactly your points 2 and 3. They cannot be overstated: they haven't even gotten the budget math to work out yet.

Given unlimited resources, sure, who wouldn't want free universities. But making it work within our real-life constraints means something else is going to suffer for that, and in today's reality it's going to be really hard to make the case that this is a priority. (Especially when many high school graduates are still basically illiterate, so only elite graduates will make it in, which means we'll be further subsidizing the elite).
