According to the article, #1 leads to "failure and drop-out rates of 50 to 80%". #2 and #3 might work for organized and motivated students, but graded assignments from other classes will be prioritized by most.
Given the education literally does not matter anymore for white collar work, I'm inclined to agree with you.
I'd rather a MUCH larger amount of professors and teachers come to class to find their classes deserted (by their own hand), and indeed, their own justification for existing gone. The world would be a lot better off. Gatekeepers are anti-human.
Then their parents come in and complain about where the $30k that semester went. This is a consequence of the exponential rise in tuition. You're now in lawsuit territory if you don't deliver the goods.
