It may be beneficial from a medical perspective, but you're ignoring the obvious risks. For people with SAD, etc. there is the risk of severe stress. For all people, there is the risk of sexual assault. There is the risk of false or true accusations from students, friends, or partners, the risk of getting assaulted, physically confronted, or robbed, reputational damage, etc. The list goes on.

It's up to each individual to decide whether the rewards of in-person social interaction outweigh the risks. And it's not up to anyone but me to proscribe what my decision on this matter is.
