I don't think they should that was the point I guess. I'm not talking about indefinitely. But sending them home in March without testing (which I know wasn't realistic), without concern to anyone at their home that might have been higher risk (of which my husband's family has multiple people, including one on chemo, so that would have been a no no if there were college students in my husband's family at that time), to any concern to their home community wasn't probably the best option IF we were trying to control, contain and reduce spread throughout. I don't think the colleges were thinking about controling, containing or reducing spread to the student's home communities though.
There's no doubt spread would have occurred there in the colleges, but consider our area there's a possibility that multiple people from K-State, KU, Mizzou, etc could have spread it to here just by being sent home (and also yes if they voluntarily came home). Would they have come home at some point? Of course, but they were sent home and then no precautions were done afterwards. Our community spread in the metro started March 13th (known parameters because we know the testing has been iffy here), but it wasn't long before it spread even more. Prior to that on the KS side it was travel related and there wasn't any in the metro known but one woman in her 50s a week prior. Absolutely more prevalent the testing higher numbers. But we stopped being as careful about testing when the community spread occurred because we needed to ration those tests. By the way heard we were getting 50K test kits. I'm hoping that helps out our area
I do know that KU had advised students traveling from Italy in early March to self-isolate for 14 days upon arrival back home. I don't think colleges who did this all made a point to say that for all students who were leaving for home. Maybe the thought process was "it's not that high of a priority" but that's because the consideration for asymptomatic carriers may not have been thought of. I'm not invalidating your concerns about OTC meds, non-family members, etc. I do think the higher priority always should have been to reduce the spread and how far reaching it would get. I recognize not all will agree with that.
