True thatI totally agree! But imo, preventing students (who have essential reason) from traveling is not a good idea. Canada has exempt international students from US, then why not all around the globe? If students don't show an essential reason to travel, then sure don't allow them entry. But they should definitely allow students with in-person classes, returning students, labs, workshops, etc. All I am saying is that they should remove this March 18th' 2020 barrier.
