Why not a ban on personal travel outright? No one needs to take a vacation, and you don’t strictly need to see your family either. Maybe we could have some kind of a permitting system where you could apply for permission to travel to see, for instance, your dying parent. But you would need to submit a letter from a doctor stating they are likely to die in the next 7-14 days, of course. How about a ban on recreational activities like hiking and skiing? If we’re serious about this being an existential threat, this should be an easy decision. Maybe a ban on human existence altogether.
