Earlier quoted context omitted.
In Australia Universities that have remote study have places where people can do proctored exams in large cities. The course is done remotely but the exam, which is often 50%+ of the final grade, is done in a place that has proctored exams as a service. Can't this be done in the US as well ?
Variations in this system are in active use in the US as well. Do you feel it is effective? It seems to me that there is a massive asymmetry in the war here: proctoring services have tiny incentives to catch cheaters. Cheaters have massive incentives to cheat. I expect the system will only catch a small fraction of the cheating that occurs.
So to your point, it’s easy to cheat even if the proctor tries to prevent it.
