This is an example of a very limited social darwinism. Basically the idea is to remove a lot of enforcement and rules in some activity, or maybe even all, and then "free market" will regulate itself, with "deserving" students managing to manage themselves, and "undeserving" ones lets behind. But the point of the university is not only teach English grammar and math operations, but also to work in teams, manage yourself, etc. The social stuff. And I suspect a significant number of students benefit from it. And I also suspect that by doing this at scale, the whole society benefits on average. Removing all control and only checking the knowledge during the exam would lead to a lot of students never catching up. It is likely that it will also lead to the top students being more and more lax and eventually also falling behind. The whole idea hinges on the base motivation - why do we need primary/secondary etc. education at all? To produce a dozen elite self motivated geniuses per year per country? Then your proposal would work perfectly. Or maybe motivation is different?..
