Such precautions are neither inherently wrong nor right. But if they have a strong side effect of hurting the student, without protecting the college from anything real, they are wrong.
>Let's say they stepped up and went beyond their responsibilities to help
Beyond? I strongly disagree that it's beyond their responsibilities to refrain from banning a student in good standing from campus.
>How exactly does that help the rest of the student body
I can make the same argument about every group. Now nobody will help. We're definitely not better of in that world. NIMBY is a bad motivator.
I agree banning a student can be heavy-handed unless he was deemed a danger to other students or maybe other things warranted such a response. But I would imagine a university has the right to remove anyone from campus and ask that they not return.
I disagree, there will almost always be someone offering to help, it's human nature. But why is it the university's responsibility to help in a case where they choose not to do so? Just because one group decides to help in certain situations doesn't mean everyone else has to help. If the university decides they don't want to help in these situations then they have that right. Some people may not like that. Some people think it makes for a better world to force others to do things they don't want to do. Force them because it's been predetermined it's for the greater good, but I see that as going too far and a huge potential for abuse.
No, I'll try to be clearer. The very idea of precautions is neutral. Specific precautions are good or bad based on whether they are likely to harm the student and/or prevent harm.

Once someone has started a degree program at a university, I would very much hope that cause is required to remove them.

They don't have to 'help', per se, but I expect them to not hinder. They are already giving away counseling, all they have to do is not interfere. Keep to the existing agreement. (Without using any "cancel at any time" loopholes they put into their contract of adhesion.)
People who are banished are cut off from social support structures and have a lot of time available to dwell on their situation which involves increased costs and delayed graduation. That increases their risk of attempted or completed suicide. Other students see the distruption and are reluctant to seek help, and that again increases their risk.
