Part of the issue is with the purpose as you describe it. Sure, at top 10 schools, a trial by fire would result in much needed “growing up” as the gifted but undisciplined (speaking for myself and many users of this site) students find their way to more durable motivations. But at the vast majority of schools, a trial by fire would end with a lot of students burned.
Perhaps that begs the question, if those kids can’t handle self-directed education, why are we putting them there in the first place, but that’s definitely a grey area, and there are hundreds of thousands of students who are smart enough to do well in higher education and skilled work, but weren’t disciplined enough to handle what you’re describing as freshmen.
Many employers pay a premium for predictably elite cadres of students. The schools want to try to pass off mediocre graduates as having some of the elite special sauce even though only a small number of students have what it takes. We know exactly what to do to produce elite cadres by aggressive sorting. But the incentives created by the federal government encourage the institutions to extrude mediocre students like a chicken nugget machine produces processed meat product. Every hot student-nugget is worth a tens of thousands of dollars a year in freshly printed loan money directed towards administrators and rent on dorms and apartments irrespective of quality; so the incentive is to stuff the students with filler.
